Well I got my first look at the TH-58PZ800U yesterday. A local store just got it in. One word, FANTASTIC, I spent a half hour comparing it to the TH-50PZ800U (just as good) and the TH-58PZ700U (the TH-58PZ800U is much sharper than the TH-58PZ700U).
One Very interesting note, the store had it set to Vivid so I asked them to switch it to THX, MUCH Darker, more so than the TH-50PZ800U, I think the only way I would want to watch it is set to the brighter Vivid mode, does anyone think this will cause burn-in over time?
Now, if I'm going to always watch it in Vivid mode, I may as well just get the TH-58PZ850U and have the added benefit of the Pro Setting and VieraCast, decisions, decisions, anyone have any comments on the tradeoffs?
