There are plenty of DS games to get/look forward to: MariokartDS, Metroid Prime Hunters, FFIII, Super Mario DS, Need for Speed Underground, Pokemon Pearl-Diamond and Age of Kings DS. The majority of those have multiplayer/Wi-Fi making the experience even better.

I don't see why they would release FFIII on PS2. I reckon there would be more sales in making it on a DS instead of a PS2 release. Mainly because so many Japanese have a DS.
