@Jeff - Samsung already sells an LED-based DLP set (several actually). I have one, and it's great. It's not as simple as swapping out a bulb, though. The standard bulb DLP uses a white light that gets its color from the spinning color wheel, which then hits the DLP chip. In the case of their LED sets, they actually have separate Red, Green, and Blue LEDs which shine directly onto the chip. So there's no color wheel at all. Not to say someone won't someday come out with a white LED replacement bulb for a lamp-based DLP, but that doesn't appear to be the direction that (at least) Samsung is going with LED technology.
