for those of you wondering about input/gaming lag i've had the set for two weeks and pretty much constantly game, so here's my completely unscientific report.
when i first got the tv i played some halo3 and was having a terrible time with AMP turned on so i turned it on and it was instantly better, about the same feeling as my old Aquos LC37D90U. after i located game mode in the menu i tried it and it seemed better; maybe it wasn't, but it certainly wasn't worse. i now play with game mode all the time and i do not notice any laggyness.
i played rock band 2 a bunch this weekend and left it on Clear AMP and it was awful. i realized the game was calibrated to my old tv so i ran the game's calibration. video lag was in the 70-80ms range. i tried it with amp on/off (Clear) and game mode on/off and didn't notice any difference.
my verdict: works for me. i can't say for certain that it's more or less laggy than whatever is the best set for this, but it is certainly not worse than my old set.
