Just looked at the new Samsung and Panasonic plasma panels last night. Both are 1080P, 50" with multiple HDMI and both sport 15,000 dynamic contrast ratio. They were both about $3000 each, which is only $100-200 more than the 46" LCDs.
The content they had playing on the plasmas was SD, and surprisingly it wasn't as bad as it appears on LCDs, but still had bad artifacts. The HD content was pretty nice on both of them. I wish they had a Pioneer Elite to compare to there, but they didn't.
This particular store had the Samsung 4665 and the Sharp 92U on display also, but they were in two different rooms so it was hard to compare content directly. Both of these LCDs look astonishing with 1080 HD material, although the sharp does show some artifacts in the darker shadows, even with 1080p source. Neither one looks so hot with SD source.
Anyone know more about these new plasma panels?
