It seems like all is forgiven between Fox and Marvel with respect to the X-Men. First Jean, now Wolverine. Think they'll bring back Charles and Scott, too? The big surprises with Legacy do seem to all be X-related.
Something's happening with Xavier is current issues of Astonishing X-Men. Not sure why, but I've been thinking it'll end with Xavier's mind in Mystique's body.
Not even sure why Xavier really needs a body, tbh. He could just float around the astral plane as a giant head and help out.
