Yeah, if that ends up being the only book featuring Diana as Wonder Woman it'll probably have them, but that book is going to dealing with the full JSA roster so I'm not really expecting much from the supporting cast.
I guess those aspects of Diana don't matter as much now if she's not going to be a leading lady anymore.
I think part of my problem is introducing new "main characters" when DC hasn't quite capitalized on the characters they've been trying to promote as "main characters" right now, or the old "main characters" like Wally, Dick, etc.This is mostly my thinking too. Breaking out new characters is hard. ANAD, while hated a lot online, did a lot for diversity in Marvel. I know of more than a few people that took up comics for that Jane Thor. And now she is going to be in a movie and guess who holds the Captain America shield now.
If it a sticks (VERY big if) it'll add new story potential to people that'll be the "main characters" of the universe.
If it doesn't stick, I still think it could elevate these characters to a good degree of relevance. If done right.
Like, is this new Flash going to make up for how DC treated Wally in favor of Barry? Are we just going to drop every other Flash?
Will the new Wonder Woman make up for all of DC's bungling of Diana?
Will making Jon Kent as Superman go over any better then aging him up and taking the Legion away from his dad to give to him?
Will Aquaman's rise to stardom be impacted by replacing him so soon after his rise?
Luke might be interesting, although Superheavy didn't really bump Gordon up that much. But even from day one it was pretty clear the mantle change there wasn't going to be permanent.
I think that's heavily dependent on how many books DC is willing to publish.
