Gamespot is currently running a feature for “Shin Budokai” (PSP) on their front page right now. Something you may or may not already know about the game is that its story mode will draw elements from Dragon Ball Z movie 12 (out in the US next month):

As with the previous DBZ games, Shin Budokai will draw from specific story arcs from the long-running series. In this case, the game will draw material from the upcoming feature film Dragon Ball Z: Fusion Reborn, which follows Goku’s attempts to deal with a threat to the universe that will require him to buff up his already impressive skills. As a result, you’ll find a game roster that includes a mix of classic and more-recent additions to the mythos. Besides Goku, you’ll be able to choose Teen Gohan, Gohan, Vegeta, Trunks, Krillin, Piccolo, Frieza, Android #18, Cell, Kid Boo, Cooler, Broly, Gotenks, and Pikkon initially. As you progress through the game you’ll unlock some fighters as well. Each character will come with their own set of unique moves and special attacks that you’ll need to master in order to kick butt effectively.

Additionally, the Japanese voice cast will be selectable!
