I've no idea what I'd be doing with a touch pad in a game, so it mostly sounds like something new for the sake of it. Sixaxis at least did have good uses in a number of games and one could envisage how such functionality could be used. One advantage over the WiiU is that every controller will have it, not just one per console.

Slightly bigger controller, fine but personally I don't need a bigger controller.

Change L2 and R2, yes definitely needed.

You'll have to wait and see, I guess.

I love Sony but this touchpad sounds really unnecessary to me. Even more so now that there is no record/share button or whatever. I guess I should just have faith but honestly this sounds really gimmicky and unneeded.

Very few in game uses aside from swiping and pressing. Thing the touchscreen use on the Vita for games like the upcoming Killzone. Slashing to knife. Or how about for the occasional wall smashing to push down on the touchpad instead of pushing X or O or whatever. Maybe if the PS4 comes with a camera and the controller acutally has those LEDs on the front, it could do things like the ninja throwing star on the Wii U. So maybe you could aim grenades by holding down the touchpad and moving the controller to change what angle you are throwing it at, which might be pretty effect compared to a lot of FPS that have you look off into the sky and guess how you are throwing it.

To me it sounds like the best way to navigate through an OS and would make web browsing 100x better than what we have for the PS3.

I guess it could be and we really don't know much about it. Though, wouldn't someone who is concerned with web browsing just buy a keyboard and mouse to use with the console?

I keep imagining there will be a Japanese touchpad game where you rub a nipple or clit for maximum stimulation

Too much of a hassle to be honest. Having to move it around, all the cords, find good position to use the mouse etc. It's just much easier with just the controller and the touch pad could also be used to make navigating around easier.

That's kinda bulky isn't it?

Plus, it's virtually a mouse, which will improve fps gaming dramatically. Only question is how comfortable it would be.

I don't know about you guys but I REALLY like this concept design for the controller.

The white trim on the analog sticks is awesome and the touch pad is not too big but also not too small.

Maybe if they make the controller wider they could fit a larger touch pad, like this
