I know people are bummed about there being no FFH wave, but if it means 78 is classic comic book stuff, I'm all here for it!
I really just want some gaps filled in my collection. If we see an Avengers wave, I'd almost kill for a Jocasta. Would love a classic Mockingbird, Attuma, & black and yellow Wasp too. Throw in whatever IM/Cap/Hulk rereleases you need to to make it happen.
If we see a F4 wave (which I slightly doubt for some reason... the embargo seems to have hit F4 hardest) I'd really like to see Dragon Man, Crystal, Medusa or even a F4 She-hulk thrown in for some diversity.
If we're looking at an X wave - anything that helps us finish off X-Force line-ups or gives us 90's X-Factor would make me do a little happy dance (So long as we see Random and Val Cooper in there somehow). @Valo487 was talking about an all villains wave. I could get down with that! lets see: Stryfe, Exodus, Sebastian Shaw, Deathbird, Harvest/Phalanx, Bastian, Danger, Cassandra Nova! #nevergonnahappen
