Wolverine was in the original trailer so here's hoping they do an X-men Playset, I guess a GotG playset is also likely since they were in that trailer too.
This was in the press release:
Playable characters will include Spider-Man, Nick Fury, Iron Fist, Nova and Venom with additional appearances by White Tiger, Black Cat and Luke Cage.
I wish White Tiger was a playable figure since they need more than BW as the only token female super hero.
Found this pic that shows the GotG also:
