I wouldn't worry about that at the moment.
I'm working with the companies that manufacture 90% of the worlds TV's and DSTB's, all of them now understand that games can run on their hardware, good games at that, and all of them are looking at the issue of gaming input.
If one of them does the gamepad they have sent me a prototype of, you will be very happy. Very happy indeed. Far better than an Xbox game pad
