Well, here's a bit of an odd one. A recent patent application from Sony has not only revealed an LCD-based game controller (which would be notable enough in itself), but an LCD-based, universal game controller that's designed to work with more than one game console. As you can see above, the touchscreen would be able to accommodate various buttons and layouts for different consoles -- Sony even curiously mentions consoles like the Amiga CD-32 and Atari Jaguar (for emulation, perhaps?), in addition to Microsoft and Nintendo -- and the screen itself would be housed in what Sony describes as a "game controller skin." Of course, this is still just an application for a patent, and we're pretty sure Sony is focused on another controller at the moment.
