I just want to reiterate that I think the big reason we didn't get this book sooner, and the big danger of the book going forward, is that this book will overshadow all the others and be the only really 'important' one.
I'm always one of the more cynical ones here, and a part of me thinks that a lot of Council shakeups people are suggesting sound more 'endgame' kind of thing for Krakoa. I don't think Sinister is going anywhere until this whole thing is about to end. Colossus though is in the Percy plot prison and that could go away anytime.
