I HAVE AN OFFICIAL rumor FROM PANASONIC!!
Last week I sent Panasonic a question on their website form, I told them my company was looking to buy a few plasmas for R&D and marketting (which actually is true) and I wanted them to get the 7UY if it comes out before they are ready to buy.
Today, a rep from Panasonic called me back. Really nice guy and told me that they were having a meeting mid September where he would be learning everything about the new models. Until then, he could only say there was a rumor that the 7UY would be out late Spetember to early October, and he wouldn't know all the specs and pricing until after the meeting.
So I actually learned pretty much nothing. I just thought it was really cool of him to bother to call, let me know they got the message and would respond as soon as they knew more.
