In somewhat interesting news (especially based on the shipment figures of the first game and the general state of Namco-Bandai at the moment), Raging Blast 2 for the PS3 and Xbox 360 has been formally announced through the pages of Jump:

There is not a whole lot to talk about just yet. We are being promised about 90 characters (the first game had just over 70, which includes all of the various transformations when appropriate), and it looks as if the graphics engine is getting a nice little overhaul. The game is due sometime this year in Japan, though no specific time frame is given.
