I just got home from work and looked at the XboX One controller. It's about damn time someone put that useless space under the controller to use (although Valve sort of revealed something like it first, and I don't count the N64's Z button because... well... N64 controller). I just hope the D pad isn't complete ass. I wish you could swap the D-pad and left thumb stick around because I'm more used to the Sony layout.
Now... is any game ever going to take advantage of the extra buttons? I remember the XboX controllers (the original Xbox, not the XboX One which is not the first XboX, that one came after the XboX. Obviously) having 6 face buttons on the right side... heck I remember the Sega Genesis and even the N64 having 6 face button. What's wrong with having 6 face buttons? The extra two buttons wouldn't be for super-necessary things you access all the time, more like the grenade switch function I remember being in the original Halo game.
EDIT: I'm watching an MGS5 trailer right now, and in the first few seconds I knew something was... different
In fact, I believe it's the first 60fps trailer I've ever seen, gameplay or not.
How are people unable to tell the difference is beyond me.
