I just replaced one....

I just replaced the color wheel on a set that only has about 500 hours on it. When the set was cold, the motor in the wheel sounded like a big electric drill that had gotten bound up. It would quiet down after a while. This seems to be a common problem. That and the lamps burn out after 4000 to 8000 hours. And when that $300 lamp burns out, the customer chews my butt, not the sales person who didn't tell them that using the TV to listen to the digital music channels was a bad idea.
The longest lamp life I have encountered is about 7500 hours, but I know a guy who replaced one that lasted about 10000. I've seen a bunch that died at about 4000 hours.
DLP is an amazing technology, but it does have a few weak spots. I'm looking forward to seeing how the solutions work out.
