During today's In-Store Convention Kick-Off event, Marvel revealed that Cullen Bunn will write an X-Men tie-in for the forthcoming Civil War II event.
Details were spare; it's not clear who will draw the story, although Brandon Peterson might be a good bet since he did the cover.
The title will reportedly not affect any of the other X-Men books, although presumably the fallout from Civil War II will impact the whole Marvel Universe.
You can't even tell much about the story from the characters featured, as almost every major X-Men character seems to be either represented, or potentially represented in the blurry crowd shot behind Magneto, Psylocke and Jean Grey. That said, the two halves of this image could easily be interpreted as split factions of Marvel's mutant community.
Marvel's original Civil War event had tie-ins and miniseries for nearly every major character in the Marvel Universe.
