While I doubt it will happen, I'd love to see some kind of retro Capcom announcement tomorrow.
A Marvel vs. Capcom collection would be great (I know they licensed some of those games for home arcade cabinets, but I'd love to see a collection with X-Men: Children of the Atom, Marvel Super Heroes, X-Men vs. Street Fighter, Marvel Super Heroes vs. Street Fighter, Marvel vs. Capcom 1, and Marvel vs. Capcom 2 on the Switch), and while it's a long shot, I'd love to see a re-release of their JoJo's Bizarre Adventure fighting game.
While it doesn't qualify as retro (it came out in 2015, with the original game coming out in 2008), it would be great if we got Devil May Cry 4: Special Edition on the Switch. I've played the base game of DMC4, but I haven't gotten the chance to play the special edition yet, and I'd like to see how Trish, Lady, and Vergil control in that game.
