Wii U like patent from Sony?

Games Beat has revealed a patent from Sony in 2010 that has a concept just like the Wii U. The patent is Titled Position-Dependent Gaming 3-D controller. Here is some details about the patent:

Methods and systems for using a position of a mobile device with an integrated display as an input to a video game or other presentation are presented. Embodiments include rendering an avatar on a mobile device such that it appears to overlay a competing user in the real world. Using the mobile device’s position, view direction, and the other user’s mobile device position, an avatar (or vehicle, etc.) is depicted at an apparently inertially stabilized location of the other user’s mobile device or body. Some embodiments may estimate the other user’s head and body positions and angles and reflect them in the avatar’s gestures. 

Wii U has pressured Sony to release Playstation 4 sooner

PlayStation Europe boss Jim Ryan has confessed to Eurogamer that Sony would perfer to launch the Playstation 4 sonner then later due to Nintendo’s Wii U being released after April 2012.

“I think we would consider it undesirable to be significantly later than the competition [with the next PlayStation].”
