I doubt it. I think I'll be done, or mostly done. I may even be done or mostly done as soon as they kill off New52 Superman if they haven't pre-announced a return (And that he'll be the focus of at least one on-going book when he returns) by then. I feel strongly about this.
That said, I don't like to put myself in a corner that I might regret later. I don't want to feel I can't read them if I decide to, just as a matter of pride because I said I wouldn't, so I'm not going to say I definitely would be done with Superman comics, just that there's a good chance that I'd be done with them.
I had been subscribing to all the Superman related titles. I've already dropped 3 (Lois and Clark, The Coming of the Supermen, Justice League), and 1 more (Batman-Superman) has ended publication. I am going to drop, in sequence, Action Comics, Superman-Wonder Woman (Which is admittedly the last issue anyway), and Superman as they have their last new52 Superman issues over the course of the next month. Plus, American Alien ends. Then I'll drop Justice League of America whenever it's Rao arc finishes (That might go into next month, I don't know).
If they hold off Superman's death for the line-wide 70 or 80 page Rebirth book that's $2.99, I might get that, or I might not. Actually, that's the same thing I'd say if he were already dead before that- I might get it, I might not. However, the odds of me getting it are much higher if my Superman is in it.
After that, my plan is to look at the individual issue covers and short summaries on the web, maybe read some threads here or reviews, and see whether I feel like buying them each individual issue or not. No subscriptions. Just decide on each issue. And if I don't feel like looking (either a particular week or just in general), I just won't buy that week, or in general. It's not my job to evaluate Superman issues for personal buyability, you know? I'll check if I want to and just forget about it if I don't. I could wind up buying like half of them, I could wind up buying none of them.
It could be that I won't buy any, but then go back and buy them all if they go on sale for 99 cents or $1.50 each or something. Maybe I'll buy some and not others as they come out, and buy the ones I passed on when they go on sale. Maybe I'll buy none of them at all ever, on sale or not.
DC Comics has no loyalty to me and to fellow fans of my favorite character, I see no reason to have any particular loyalty to them.
What could they do that would appeal to me short of bring back new52 Superman and restoring him to his rightful place? Well, nothing that'd be equal to that, obviously, and automatically get me back to where I was before. However, some basic things that would appeal to me along those lines are:
1. Them killing off the Jon White (Kent?) character in the comics, having Jon just be a regular non-superhero kid who is only a minor character who is seen when Superman is hanging out at home, or them pushing all of Jon's superhero stuff out of the main books and into SuperSons (Which I will never buy a single issue of, ever) and left unmentioned completely in the main books would be three options that would help the main Superman titles appeal to me more than the current plans seem to (How much more, I don't know, but more). Doing a Superman book that was announced as not featuring Jon ever would be appealing to me (Relative to the current post-Rebirth plans that I'm aware of), even if it was about his father rather than the new52 Superman.
2. Bryan Hitch is writing one of the best or maybe the best ongoing featuring new52 Superman right now, Justice League of America. He's going to be doing the regular Justice League starting in July. Combined with a great author, if I see that those issues have no Jon in them (and no Damian- really, this isn't asking a lot for a *Justice League* title, which doesn't usually have side characters featured, because it has 5 or more main characters to balance already), that'd help. A Justice League that is initially mourning new52 Superman and suspicious of SuperDad and has angry words with him would help.
Then when they do finally accept him not just just acting like he's always been there, and them continuing to remember the real Superman would help. It'd also help if they avoid the sort of shadow ret-con route of after a while just never mentioning the new52 Superman, never mentioning SuperDad's other universe-like origins after a certain point, and describing the past without mentioning that it was another Superman was there. I want new52 Superman to keep getting mentioned where appropriate and I want them to always point out that SuperDad isn't from this universe where appropriate. SuperDad doesn't get to be the leader, he isn't their Superman, he's just a new superhero from another universe they are breaking in, after they come to trust him, which should not come easily, and should not come at the expense of them remembering new52 Superman.
3. In general on these titles, it helps if something that's interesting to me is happening and not something boring. I'm describing that kind of broadly, so let me be more specific. The book titled "Superman: Rebirth #1" is about Superdad being worried about his son and chasing someone who's after him- I'm unlikely to get that. Then the first two issues of the Superman title have solicitation descriptions that are all about Jon directly, like parenting issues and Jon using his powers to fight people, I'm even less likely to get them than the preceding story. The third issue (or fourth, if you count the "Superman Rebirth" one) features Eradicator, but hints that Superdad loses to him and Jon beats him, which gets plus points for actually having a freaking Superman-type plot, and minus points for SuperJon (aka a pre-teen never-aging Wesley Crusher) saving the day, so probably is about at the same level of not buying.
The Action Comics solicitations post-rebirth that seem to involve mostly the other universe's Superman interacting with Lex Luthor and fighting Doomsday and doing, well, Superman stuff, and there being a Daily Planet angle (I like the journalism aspects of the Superman mythos that they keep ignoring) with a Clark Kent who is not Superman and Lois Lane trying to figure out who this weird older Superman is, those seem more like issues I'd consider buying on a surface level. However, that's relative to the Superman issues mentioned in the previous paragraph. I still don't like that Superdad is in them and I don't entirely trust that Dan Jurgens, who created the Jon character and evangelizes him and talks about him being his Legacy in DC Comics and making sure he's all over the place will really give us stories that aren't about him. I may ask around the forum on release day and see what the people who buy them can tell me about the level of "Jon" content and then consider getting individual issues if it's really low- or even waiting out whole story arcs and then asking about how much Jon figured in, and maybe getting those arcs if the answer is "Almost not at all".
It's sort of ironic that in the early going the Jurgens series issue soliticians seem to feature people like Luthor and Doomsday and less Jon, and the Tomasi series issue soliticians seem like the book should be titled "The Adventures of SuperJon", isn't it? I mean, considering Jurgens is the Jon character's creator and biggest advocate, and loves writing SuperDad, and Tomasi as far as we know was just told "Here's the new status quo, go write us some books" and could have been against the death of new52 Superman or SuperJon or whatever as far as we know, it's really odd that Tomasi gets stuck with what seem like the "It's tough parenting a superhero 10 year old who's better than Superman" type issues. I guess they were probably assigned to him because he wrote that Damian book (I also don't like Damian and never read an issue of that) for a while.
Anyway, I already am taking it as a given that new52 Superman won't be back permanently to take back his rightful place unless sales flag. So, no difference if they announce it now or just stay silent. I'm not going to let them win sales from me with what may be false hope. The announcement that new52 Superman will definitely come back and take the books back in a set period of time and that SuperDad would be retiring or going back to his own universe or whatever at the end of the story arc, would have saved probably all the subs. I can sit through a story arc that has it's bad points. But they aren't saying, and are implying this is the new status quo, so I am assuming it is, and going from there.
