Not really, I've seen how Nintendo DS is, it sucks.
What I thing would be kinda fun is if Playstation came out with a game that was kinda like Super Smash Bros. Melee, except it starred all the popular Sony Characters (Crash Bandicoot, Lara Croft, Jin Kazama, etc.), and some of the Squaresoft crew. (Cloud, Squall, Sora, Yuffie, Riku, etc.)
