Just letting everyone know that this game is cheap cheap cheap on XBLA right now. I am too lazy to boot up my PSN to see if they're doing a Capcom sale but this game has the biggest discount. I think it's safe to assume it's also on PSN since it's a publisher sale. It's showing up as $3.74! (I'm in the beta)
EDIT: Actually I can only find info on 360 versions. I don't think Capcom is having a PSN sale.
