The only thing that would dissuade me from a 360 game purchase is if the PS3 had extra content (like Lost Planet or Eternal Sonata or Stranglehold) or if the 360 had to have multiple DVDs versus a single Blu-ray.
It'll be interesting to see what GTA:IV does. With the extra space on the Blu-ray and the guaranteed HDD, will the PS3 version be a more seamless experience than the 360.
