I've been hounding Zak on XVerse to give me hints on his next project for MVL and he led me to believe it was one of the Paramount pics. That turned out to be Avengers! So that will come after Hulk 2. Good news for Hulk 2 fans is that he already has a treatement for it!
So that wraps up his 3 projects.
1) X-Men spin-off
2) Hulk 2
3) Ultimate Avengers
