There have been rumours for days now that Marvel vs Capcom 3 was announced at Capcom's Captivate '10 event, which was held in Hawaii last week.
Well, even though everyone knows those rumours are basically true, they've definitely been confirmed now as the official teaser trailer for Marvel vs Capcom 3 has been leaked onto the internet early (embargo is later today).
Check it out before the plug is pulled. And yes, that is Chris Redfield from Resident Evil fame. I wonder if Jill Valentine will be returning?
