If money is no object and you do most your viewing in an appropriately dark room, the Pioneer Elite Kuros are pretty much by common consensus the best displays you can buy, period. However, for roughly half the price you can get pretty close with a top LCD set, like the step-up Samsung A950, or a Panasonic PZ800U plasma. Honestly, though, unless you are really, really picky you'll probably be very happy with the set you linked.
As far as prices go, I don't see them heading any way but South in this economy. The longer you can wait, the cheaper you will be able to get just about anything in the CE universe. My gut feeling is the floodgates will really open after the retailers take stock of how miserable their Christmas season actually was. In a sink-or-swim situation, excess inventory is two boots full of water. They'll be pretty much throwing flat panels out the front door, I reckon.
