AFAIK, it officially launched back in the November with a MSRP of $6999. Then again, I suppose pricing is irrelevant unless there is a supply, and again
AFAIK, I have yet to actually see any readily available stock. I have heard stock might become available in April, but YMMV.
My thoughts? Buy a high-end LCD television for less money, or that $6999 could even be spent on a decent front projector setup.
