I'm not entirely sure but I would guess it has to do with keeping costs down ... I would imagine the DLP chip is the most expensive part in the setup and since DLP is marketed as a "lower end" display (lower end not necessarily meaning quality of display but cost) and making a three chip design would increase that too much.
That being said, there are some three chip dlp's on the market. Mostly used in projectors, but I think there are some tv's on the market that use a 3 chip design. Another thing that manufactures tote is that by upping the color wheel to 5+ colors, they can produce more natural colors then a 3 chip (and in turn 3 color) design which may or may not be true.
“Getting too close completely blurred what we saw to the point of incomprehension, but again, this shows a whole heap of potential that's fascinating to us.”

Q: Why are most if not all LCoS/SXRD 3 panel based while they are still stuck in the one panel + colour wheel for DLPs.
