Sabretooth... Back from the dead, and such.
Confirmed by Marvel at NYCC:

"If you go back and actually look at 'Evolution,' and particularly the last issue of that story, it is there. We did leave bread crumbs along the way. It's not going to be a time travel trick."
Also makes mention of possible rumblings of the "we know it's coming, just get on with it" Phoenix revival:
Apparently, Creed's book is going to be written by Loeb and drawn by Bianchi.
