This issue of X-Men Prime is the first step in the process.
It fulfills its duties - it checks in with the original version of the team (reunited at last and on the run), sorts out the leadership of the "New" X-Men, checks in with an unlikely team of "heroes" (coming soon to another title), and finds an incredibly unlikely home for the School for Mutants.
It's all put together by a small army of writers and artists, and to be perfectly honest - it's almost completely unnecessary.
You could easily skip this issue and pick up the upcoming number one issues and you'll (probably) have no trouble catching up.
It's not a bad issue, but it feels suspiciously like an overpriced ad for the new family of X-Comics.
