You DO know that the worst selling (full) Gran Turismo game has sold better than the best selling Halo game?
Gran Turismo 4: 9.59 million sales
Halo 3: 8.68 million sales
Gran Turismo 3: 14.87 million sales
Halo: Combat Evolved: 6.43 million sales.
So effectively, Gran Turismo is Sony's Halo, Final Fantasy would be Gears of War if it was still exclusive (-.-) *looks at PS2 list*
Kingdom Hearts, if that somehow becomes a PS3 exclusive, would sell extremely well...
Resistance has shown itself to be a strong seller, as have Uncharted and Metal Gear Solid.
The PS3 has plenty of IPs, just not a lot of them have been released yet.
