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.)
Soren is right, the DS does suck. I have it, and really do not play it all that much. The consoles are much better if you ask me. I like the controllers better, and having it on the tv helps (with the DS, your neck hurts a lot) I most likely would still buy a KH game for the DS anyways though. But, I hope it does not come out on the DS
