FWIW, here in Japan, the Fujitsus don't sell very well now because they are not price competitive and the picture does not seem noticably better for HD use. NEC just sold its PDP mfg. business to Pioneer so anything which comes out will not be NEC original. The two main contenders in Japan at the 42-50" sizes are the Panasonic and the Pioneer. Every time I have compared the two (and I have been comparing them for 3 generations now, waiting, waiting, waiting for the price to drop), the Pioneer always comes out on top for color but the Panasonic may have the edge in blacks in a light room. The new Pioneer runs quite a bit cooler than the Panasonic does (and uses less electricity) and is about 33-40% lighter (42" or 50" version, respectively).
Personally, I much prefer the colors of the newest Pioneer (505HDL) vs the newest Panasonic (50PX300). Both "new" versions noted above are only about a half-generation technological bump from the last model (they were brought out for pre-olympics sales campaigns). I would not expect a 'real' new generation screen for at least another 6mos (in Japan, perhaps longer for the U.S.).
