PS3 Can't Play Used Games!?

[WeApOn]

I just got off the phone with someone from Gamespot, and he said that PS3 is rumored to not play any preowned/used games. I'm not sure if this was known before, but it was news to me. Again, this is just a RUMOR.

If it doesn't, it would probably use games like Steam does for HL2 and other Steam games, registering a game to a user or particular system. That would suck if you wanted to bring a game to your friends house. But it would be cool if you could just log-in and play it. I'm not sure if this will happen or not, but if it does Gamestop and EBGames said they may not even sell the PS3, since pre-owned games are pretty much what they're all about.
