...I'll see myself out.

PS3 and PS4 use the same standard USB interface. You lose access to the share button and touchpad (so if the latter is heavily used in Destiny you'll be SOL) but otherwise wired devices should be good to go.

All subject to confirmation, of course.

Supposedly these will be made for the PS4. From @AngryJoeShow

I wonder where the touchpad will go

1.) It looks tiny! (look at the size of the USB cable in comparison.)
2.) As you said, where's the touchpad?

Personally, I'll stick with the PS4 controller until a better third party comes out.

On a related note...

People should never have, "I don't like the controller" as a meaningful reason not to game on a specific console.

First of all, you'll get used to any controller if you just use it for a couple of hours.

Secondly, there are usually a whole HOST of third party accessory makers that make X-style controller for Y console. (And I can only see the offerings of such controllers becoming more and more commonplace.)

Seems Legit.

Am I the only one who noticed this?

Nope. You weren't.

I wonder where the touchpad will go

Even then though, PS has had pressure sensitive buttons since at least PS2, (maybe earlier, I only know of Metal Gear using the function)

Gran Turismo 3 had it too, much to my demise. How the heck was I supposed to know the stronger you press X, the faster the car goes? It's like saying turning the controller makes the car do sharper turns...
