Some of this information was already available, but there's something to be said about starting off the new year by letting the world know where everything stands. Capcom's gone and done that with a press release devoted to release info and windows for its upcoming games.
Those are the firm dates. The company also has some sketchier windows for some of its other stuff. Flock!, the sheep-herding UFO game will be coming to Xbox Live Arcade, PlayStation Network, and PC in "early 2009." MotoGP on the Wii will hit in the middle of March, and Bionic Commando will be available on PlayStation 3 and Xbox 360 during "the first half of the year."
PC versions of Bionic Commando and Street Fighter IV were also mentioned with non-specific dates. They'll just be coming sometime after their console counterparts.
At one point, Capcom was making a little bit of unofficial noise about Bionic Commando coming in January, but it sounds like that's not happening. Joystiq is reporting that Capcom put out a similar list for the European market that pegs Flock! down to February and Bionic Commando down to March, but my guess is that the wider, less-specific US info supersedes the European news.
