I think it'll be a classic case of DST kicking us in the face. Here we just get a kick-ass wave 60 and then we have to wait like 6 months or so for 61.
If that's the case, It'd better be classic Avengers. That way, we can have an Avengers 2 cmic tie-in like we did the Winter Soldier, and have enough 'mates to hold us over until DST decides to release the AOU figures.
That being said, I'm gonna say It isn't straight Avengers, but West Coast Avengers/ Avengers West Coast:
US Agent/ War Machine
Master Pandemonium/ Tigra
Vision/Wonderman
Mockingbird/ Hank Pym
We just got Hawkeye in Best of 3 so, I wouldn't bank on him being in this wave.
