Who knows. I've given up trying to understand Marvel's marketing concerning new, not new but new number 1, same but with a new writer, etc. books. It just seems that, with Axis, the major through story in UA is coming to an end, leaving it in the sort of place they would typically relaunch a book.
It could be relaunching but the new book they are talking about is something else, though. If that's the case then I would bet on a Wanda solo.
Yeah. I agree that Eros' powers and ethos would make him a good advocate for unity. I do, however, also think that given fans...visceral reactions to the unity team, it's mission and it's membership having someone with no prior connection to the idea of mutant rights like Eros could end up backfiring on him. Returning after so long an absence, Eros really needs to be reintroduced to the majority of readers, and I question whether UA is the right venue for that. A more traditional Avengers team might be better suited for him to return to.
Jocasta? Man, the Zombie books really mine the obscure characters, don't they? That said, she should probably be added to my "severely underutilized and desperately in need of a return" list. The Avengers do seem to have a lot of those, don't they?
