Eurogamer has done some interview with the people that made the Wii U Gamepad to work with the PC and they gave pretty good information on how it works, and it turns out that most people's speculations were right with the wireless N part. The really cool thing is that the input itself is registered 180 times a second back to the console, that's not too shabby at all!

Secrets of the Wii U GamePad

Digital Foundry on how the controller was reverse-engineered - and exactly how it works.

Hackers have emulated the GamePad controller on PC, and they tell us everything we need to know about how the magical video streaming technology works so well.

The Wii U GamePad has been reverse-engineered by the developers behind the Dolphin GameCube/Wii emulator, with the controller's functions completely simulated on PC. When we heard the news on Twitter, we contacted developer Pierre Bourdon to find out more. In hacking the GamePad, we reasoned that the developers would have extensive information on how Nintendo's innovative controller actually works.

THE INPUT REGISTERS ITSELF 180 TIMES!!!!

i really dont have a clue what that means...:p

180 input updates a second is pretty damn good.

As expected, when asked about Wii U emulation, they cite the "complicated programmable GPU" as the main obstacle. Whole different ballpark to emulating the Wii's fixed function GPU.

Yeah, I'm excited, but I don't know why.

Holy shit, did anyone else see it mentioned that the controller registers itself 180 times? That's incredible. The ps3 controller only registers a dozen times, if that.

In before "the DualShock 4 will register itself 2,000 times per second, Nintendo is being left in the dust."

lets just say that the input lag is not an issue on the gamepad by a long shot.

lel.

Well, IIRC Sony said it would at least match the number of registrations per second as nintendo, but they might go with a more indepth registry while matching the speed.

I'm just happy console manufacturers are finally surpassing the Mareseilles' Input Registry Standards and not just subsisting at what's required at bare necessity

There is no reason for Sony to do it with the dual shock 4 though, it doesn't have a colored LCD display like the Wii U gamepad so it doesn't need the excessive input to counter the possibe input lag due to video/audio streaming(lets not forget that the Wii U gamepad also house a NFC chip and a mic input etc), unless the touch pad requires alot of inputs per second, we only have so many fingers lol.

It's likely for the tablet Sony will be using, if anything.
