Yea i'm sure none of them have any interest in playing games like Uncharted, GTA4, Gran Turismo 5, Devil May Cry 4, Resistance 1 and 2, Final Fantasy, Unreal Tournament, Metal Gear, Various Sports games, etc.
It's not unheard of. I actually know LOTS of people who bought a PS2 when it came out because it was also a DVD player. Not one of them ever bought a game for the system.
