Buy the pioneer. I have noticed quite a bit more "noise" in the panasonics this year. I have seen these side by side and would say the Pioneer is still much better when it comes to black levels and the single pane glass design still rules. The Pioneer 5020 is coming in at 3800 bucks, may be worth a look,claim 5xbetter black levels than the 1st Generation Kuro's. But I have yet to display the new Pioneer and havnt personally seen it.
