Mmmh, i dont see the point to DRM on PS3. This will definite have an adverse effect on the console market as they not taking into account that the PS3 is available in contries where internet is not cheap and online verification is not a real option. So far everyone who owns a PS3 has only orignal games, what more do they want...

Alternatively killing the 2nd market is not a good thing, taking into account that most people buy second handd when they not sure about a game. Or its sequel so you buy the first one if you like it you more than likely to go buy the sequel new because you now like the game. Also 2nd hand market also good for replacing games you broke.. They need to think about DRM more carefully i think.
