What I'd really want to see... A new Darkstalkers. Having only been able to play the PSP version, I noticed it leaves many, many character's story open. And not to even mention the promise of something happening in the future of the Darkstalkers in general.
Plus, the way Capcom keeps dragging back Morrigan and Felicia all the time, GIVE US _DARKSTALKERS_! Bring back all those characters we know and love, show some love for the legendary 2D fighting series that back in the day was (fans would agree) a true rival to such legends as Street Fighter.
(Or at least bring back more characters from the old games, not just Morrigan and Felicia all the time. Talbain deserves a spot, at least.)
