Planning on getting one of the new 65" model plasma's from Panasonic sometime this summer. I've looked and the main differences seem to be the panel used. All the "Infinite black ultra" and "30,720 Gradation Steps with DCI 98% Color Space" and "ultimate black" are more marketing than anything, but I have to think they use higher quality panels in the higher end. I'm look at the ZT60 series just because I've never had the high end sets before and would love to get my hands on one. The main thing is the size, but I'm pretty picky when it comes to PQ so I want something that will shine no matter what I throw at it. I currently have one of the older 1080p 42" sets and love it, but know it gets better than what I have. What do you guys think? Is it worth it to go all the way to the top?
