It's not just that.
It's the exclusives as well.
I have no attraction to Infamous, Killzone or most of the other PS exclusives. (Sly Cooper being the only one I really love.) Whereas, I'm very intrigued by Halo 5 and the next Gears of War Title and motherf**king Titanfall looks badass. Plus, Kingdom Hearts III was the only thing that had me thinking I might get a PS4, but since it's coming out for the One, that's what I'm getting. I don't really care too terribly much about graphics performance. As I've said, the One looks a whole lot better than anything I've used in the past, so you know, whatever.
