My personal opinion is that, also this year, panasonic plasma up to the G20 series (I have no infos about the V20, and I don't take care of the 3D VT20), are cheap plasma display as well as they were the past year, and as well as many others of other brands.
I don't give a toss about their "new" features. That one that is now creating that floating-blacks problem (i forgot its marketing name) it is not defeatable; the "super resolution" is only an edge enhancer; the "Infinite black" is another example of useless feature, and so on.
Until they will continue to use their V-Real video-processing developed in-house, I can't see how much good those plasma can be. After so many years, even this year the G20 is not able to do a good deinterlacing, and that is a REAL shame. And you know all the other strange things.. no 96 Hz on 1080p/24 on the U.S. models, GG still present, color banding still present, and so on.
Pioneer was another story.
