Thor was not listed, but lupinko disclaimed that he thought he was missing one, though he knew the roster was 38. As long as Galactus is non-playable, that makes for the 19-19.
Discrepancies: No Mega Man, which is unexpected. Hsien-ko was thought deconfirmed along with any Darkstalkers characters beyond Felicia and Morrigan. And Akuma was thought to have been discluded when S-Kill suggested there were no more shotos.
I was still expecting Storm and Sentinel, so I'm glad to see that. Hsien-ko and C.Viper I believe are excellent inclusions. I would rather Alex over Haggar if the need was a grappler, or Cody over Haggar for a Final Fight character, but c'est la vie.
Taskmaster is an interesting prospect. Could be the mind-melting style or whatever to which S-kill alluded.
