I disagree. Unless you truly believe they are just doomed. This is their last chance at beating extinction and this is the one thing they haven't done, as shown in HoX/PoX, so it blowing up pretty much makes mutant stories that try redundant, and leads us back to another lost decade or two where the worst writers do the crappiest Claremont impressions.House and Powers establishes that Krakoa remaining the permanent status quo isn't going to happen. We already know it's going to blow up, the ride is about seeing how it blows up.
Editorial wise the last time they shook the status quo up this hard (Morrison) it was already being sabotaged and retconned before his run was even done and led into what with a few exception and bright points would become the Lost Years. Add in the new status quo puts the X-Men back in the spotlight both critically and commercially in a way they haven't been in years, and at the same time they got the mutants back from Fox and Feige was given a new position putting him at the top of comics and making himself a direct pipeline between the two divisions. So don't be suprised if they decide not to blow it all up.
I am not saying it stays exactly as is but I cannot see anything beyond moving forward from here as an unforced error at best on Marvels part.
