I wouldn't be surprised. Much has been said that the new Xbox console will somehow have protection against used games as well.
See, this is something I don't understand. Gamers love Valve, they love Steam, they love EVERYTHING about Valve and Steam, and want digital distribution for everything, everywhere, often claiming they would love a steambox console or steam ON one of the other consoles. Then some news like this comes up, where Microsoft or Playstation starts talking about making their new console almost exclusively digital distribution, and everyone goes, oh hell no, their just trying to kill used game sales exclusively to kill used game sales. Steam doesn't have any type of used game market, and its hugely successful and held in such high regard. Why do we all love Steam so much, but then do nothing but complain about the loss of used games when an announcement like this is made? It makes little sense to me.
Iunno, I'm sure that I'm over generalizing here, and not seeing the whole picture/all the issues, but, well, there it is.
Oh, but the backwards compatibility thing, yea, it kinda sucks. I'm sure there's some hardware excuse for why they can't do it, when really it'll likely just be oh, well, you can download them off the PSN to play still, so, again, buy your library, AGAIN. That's not nice. I'll keep my old PS3 that still plays PS2 games that I had to hunt down, thanks.
