@novi_homines: Nighwing was also a rumor and hasn't came true.
Lazarus Pitts were suppose to show up in TDKR and JGL was suppose to be Alberto Falcone
Joss Whedon was suppose to be making a Planet Hulk movie after Avengers
Want me to keep going?
Rumors are false just as often, and probably more often than they are true.
So you don't think there will be any villains in this movie?
