I am curious too. Anyone? I'm close to pulling the trigger on a 58v10.
The performance and CNET review of the 50" V10 is obvioulsy very impressive. My home theater room is large enough that I'm looking at getting the 58" V10. Is there any reason to believe that there will be any drop in performance in any area by going with the larger screen? Thanks!
