I think "not yet" might be more accurate. The 360 is closer to release than PS3, so I guess it has move developers signed on at the moment. My reasoning for saying this: EA. You've got NFS Most Wanted as an X-Box exclusive. EA will whore that thing out to the PC as well (not your point, I know), and likely follow it up with a sequel or rerelease for PS3. Possibly PSP and NDS versions too.
