I e been predicting a game market crash for a few years now but I didn't think it would come as a result of consoles not playbg used games. If anything, this will likely make people more careful about what they buy, which may mean less games sold, and in an era where production costs are bigger than they've ever been, this is the last thing devs want.
I'll call this alarmism until the consoles come out and we know whether it's true or not. I read an article that claimed the same thing about the PS3 before it came out so maybe this is just another cry of wolf.
But even if it's true, we have thr entire history of video games available for free online. So I'm not worried. That and I've been playing most of my games on ios and pc. I just got a ps3 recently so I've got a lot of catching up to do.
