With the Tokyo Games Convention going on and more and more news and annoucements coming from many companies each day Capcom seem to be next in line for major annoucements. According to Australian site 'Game Player' Capcom has been tipped for deployment of 'three huge announcements'. Nothing is allowed to be spoken about yet but news is on the way.
Like Andy said, my guess is that one of them might be about DMC4.
As to my knowledge thats the closest big game from Capcom to an actual release. So would make sense to start revealing more info about it now so the marketing and advertising can start.
