I'm going to be that guy and probably stick with Xbox because I like the exclusives they showed more then Sony, and that's really all it comes down to for me, yeah I know it's 100 bucks more but I want to play the games I like with the controller I like, so yeah! The only thing that sucks is the digital family sharing system is now gone and I can't share games with my buddies without having to physically hand them the disc again, that's one feature I was actually looking forward to quite a bit, and now I'm not sure how running multiple games at a time will work since you need to have the disc in the tray....
That said, I'm sure I'll still get the PS4 as well, just might not get it at launch, depends on both money and 100% confirmed launch games!
