Here's my 2 cents... I have been monitoring the TV battle for a few months now, and also in the market to buying one. You are right in guessing that the price and tech battle is not yet started between LCoS and DLP guys until the end of this year or start of next year. I would wait if I were you till the end of the year, and that is if you can wait that long!
You can get some real good TVs for pretty decent price by then. LCoS and JVC's D-ILA tech seem like killer techs to me. For the TV size you want check out JVC's recently released D-ILA TV. It's absolutely stunning! Go check their website. You can get it online for half the price they advertize it for.
I would love to have a projector too, but if you are planning to have it in a living room where you are bound to have some light stream in then TV is the way to go. Colors bleed from projectors when there is light in the room even if you have high lumens projectors like you find today... and I think thats what the projectors manf are trying to work on among other things on how to make it a real competition to TVs. It will get there eventually. If you are planning for a basement setup and you can get total darkness then projector is the way to go...ofcourse, the good ones are still expensive!
Now you know why I wish I had a basement!
Enjoy the shopping.
