Hmmm…not quite sure what to think of this patent, although it looks like the Wii remote could fit in the slot of this controller.  It’s very reminiscent of the Dreamcast controller actually : )  Here are some details on the patent:

An X button 46 and a Y button are further arranged in line on the upper surface of the housing. An imaging information arithmetic unit is provided at a front end of the housing in a longitudinal direction in such a manner that an imaging device thereof is exposed from a front-end surface.

Maybe we’ll hear more about this at E3.  We’ll see..
