Sure, there's one on the Wii, but by now it's lost all the novelty factor it once had. After two versions on the DS and multiple copycats, who's really going to want ANOTHER brain training game? One that you can't even cart around with you. The real drivers so far for the Wii have been Wii Sports and Wii Play, but they're mainly demonstrations of what the system is potentially capable of, like you had in the DS's early life with Pac-Pix, Kirby, and that Yoshi game. Brain Training isn't going to cut it anymore as a mass-market driver for a new system.
