Well, this is certainly a mysterious one! Marvel has spent the past few weeks slowly teasing the "Regenesis" teams of mutants who will emerge after the events of X-Men: Schism, but the focus has now turned to another area of the Marvel Universe entirely. Basically just the Avengers logo in a crosshairs, it's unknown what exactly this means, although Newsarama speculate about the possible meaning of "X" shape rather than a cross, and upcoming return of Norman Osborn as being two possible answers. Either way, Marvel are promising answers TOMORROW!
