BlazBlue, the latest from Guilty Gear creators Arc System Works. A PSP version is currently in the works, and as is typical of many Japanese games, no US release has been announced. That's likely to change, as Siliconera has discovered a GameFly listing for the PSP version of BlazBlue.
According to the rental site, the publisher is none other than Aksys, distributors of the Xbox 360 and PS3 versions of the game. Considering Gamefly's penchant for leaking releases, this should come as good news to PSP fans.
