Apparently, the Panasonic is able to eliminate crosstalk by having a blanking period between frames when both shutter lenses are closed, and the plasma is displaying nothing at all. I don't care technically how the Panasonic engineers pulled it off. I just care that there's no apparent crosstalk between the left and right eye views.
I'm not sure the motion is smoother on the Panasonic plasma. That's my main concern. I didn't notice problems with the Samsung LCD's motion. The Panasonic, though, looked a bit unusual. I'm just not sure what it was I was seeing. That's why I'm so anxious to go back and check it out again.
The Panasonic VT20 is a 50" plasma panel ($2,500), but they will also have a 58" set. Samsung will have several plasma displays, as well, including a 50" set that will cost only $1,800. I can't wait to check out the Samsung plasmas for all the issues I'm discovering are so important to me.
As for your concerns about plasma panels, especially the recent flap about Panasonic displays that automatically raise black level, we'll just have to wait for the reports to start rolling in. AVS is a great source for that sort of thing. People here are not shy about expressing their opinions.
I'm thinking I'll probably end up with a plasma display for a bedroom until a good 3D front projector comes along. My goal for 3D is the same as it was for 2D - a real movie theater experience at home, but better. The only way for me to do that, long term, is with a projector. Until then, and while there aren't many 3D movie titles to choose from, I can live with a smaller plasma display in a bedroom (58" or more, if possible). Even the 110" screen in my main home theater room is smaller than I'd like. I just can't go any larger. I'd be willing to wager money that within a couple of years, I'll have a 3D projector in my home that will surpass the Avatar experience I had in the regular theater.
