the wireless solution is pretty theoretical though, as it doesn't make sense. You'd need an expensive wireless receiver to drive the TV, and to wire your NGP to a wall outlet. The most logical solution would be a docking bay, wired to TV and wall, with DS3 support for the controls. I suppose NGP could function as a remote or such, benefiting from the touch screen, and streaming content wirelessly that way, but I don't think the juice would last.
At this point I don't think NGP as a handheld media streamer to TV is sensible.
