This is some bad news...not only do we lose Gillen, we're forced to go to either an Avengers team with a couple X-Men on it, or a Bendis X-book with the 1960's original five?
I'm not saying we need 5 titles of just X-Men teams (or do we?), but the X-Universe is too vast and extensive to be shoved into a couple Avengers book like so much riff-raff. The X-Verse needs at least two full time (Blue/Gold though not necessarily in the same construct) teams functioning at the same time to give all the great characters their do, not to mention the X-Children.
Won't someone PLEASE think of the children?!?
