That Capcom site with no countdown, but just dates such as 1860, has finally revealed itself. The game is in fact Basara 3 (or Devil Kings 3 in the US). The game is set to launch in 2010, however, Capcom has not announced which systems the game is going to be on, but we’re assuming the PlayStation 3 and Xbox 360, or at least one of them.
As of now, you can take a look at the game’s website, featuring just a logo and two silhouettes.
