Another thing realized in my readings is that the 13g (mid 2010) Panny's should incorporate some of the stuff they bought off Pioneer. To me, its worth skipping 12g to see if they can get closer to the Kuro tech in 13g.
My 50" is calibrated and looks damn fine in a dark room (blacks), so I really should not rush the next upgrade. I mainly want a more size, and 24p playback (96hz, 120hz or 240hz) that works. The 12g's do it pretty well in 96hz (better than the 11g which flickered bad), but still have some flicker. Maybe they will work this out too.
