Who really knows. I've heard a lot about Samsung making them, Sharp, and LG. Who knows who really does, its all conjecture from what I've seen so far. But the rumors seem to most strongly point to Sharp.
Probably a combo of a couple of companies... Sammie board, Sharp controllers, etc., etc. It's like the washing machines, Samsung = LG, Whirpool = Kenmore = LG.
