So some German hacker calling themselves Chaos Computer Club had this press conference where they announced that they successfully hacked and reverse engineered the Wii U gamepad to use it with the PC.
Pretty cool if you ask me especially if we'll be able to use it with the dolphin emulator and such.
Here's a video of their conference.

And download it here (Note: It is a very buggy pre alpha version needing alot of modding to "kinda" work.) :D
