Most people I know can not afford a new game price except every once and a while. I know there are a lot of people like that, especially these days so not being able to play used games will not go over at all.
Even though I can pay full price, most of the time I do not for the fact that I find 90%+ games these days are not worth the asking price. So if they do this, I will not buy the new system, ever. The Alienware X51 looks way more interesting than any new console anyway.
