I haven't seen a 9G Elite since we stopped selling them so I can only go by memory on those. My store does still have a 5020 in the breakroom, though, so I'm pretty familiar with 9G Kuros.
I have a VT and my friend recently got a 60" GT50, and I have to say that the 2012 Panasonics are quite phenomenal. To me, they look so similar to Pioneer displays...I can't quite put my finger on it, but they seem to capture the "character" of Pioneer sets - - the depth, the realism -- exceptionally well. 2010-2011 Panasonics didn't really look quite so "Pioneeresque" to me. I believe the blacks are on par with 8G Pioneer PDPs/1st-gen Kuros, correct?
It wold be nice if Panasonic put the final nail in the Kuro's coffin in 2013. I think enthusiasts care more about achieving this than Panasonic does, however.
