I already pre-ordered my PS4 bundle box w/ NFS: Rivals. The fact that Microsoft would even consider the thought of not allowing a console to play "used" games is just ridiculous. I will gladly pay $60 for a new game, sure, no problem if I really want it. But if I have $20 laying around and I want to buy a couple cheapy used games to pass the time or try out, I am going to do it. And if your system will not allow me to do so, you can go **** yourself Microsoft.
All else aside, get a PS4. Or like what others have suggested, wait awhile longer and then decide.
Mmmmmk. I did my rant. Time for bed.
Hope I helped.... lol.
