The controller seems a bit bigger, which is good. I like the indent in the analog sticks - it beats the rounded nub any day. There's no clear view of the controller's back, but I hope Sony gets rid of the PS3's triggers. Even just buttons would be preferable.
I'm not exactly sold on the need for a touchpad, but whatever. If this is legitimate (which it likely is, at this point), it's not bad. I'll be looking PS4-ward to the inevitable announcement.
not sure what the touchpad willl really be used for. Its not big enough to work like the wii u's, so aside from some really minor like swipe movements or an added button or 2, i cant see people using it for much.
This is gonna be one weird gen, it seems everyone has some sort of built in thing to make their system different. Not sure what devs will do when they are faced with wii u's big touch screen, then ps4 mini touchpad and likely the built in kinect for the 720. Seems like development nightmare to try and do something for each one (and we know 3rd party is moving more and more away from being exclusive).
