I don’t have a lot of room on my wall but the bezel on the Kuro is 7-1/2” of the 67-1/2” overall diagonal width. It looks like the new 64” could be almost the same size with its smaller bezel.
So if it’s brighter, has less or no buzzing, runs cooler with better blacks I may have to upgrade.
While a brighter screen with better blacks can help it seems the real enemy of daytime viewing is the glare. The picture of the F8500 shows a lot of mirror like reflections going on as does my Kuro. Maybe we'll have e-paper displays and everyone be buying crazy $1000 lights for night time viewing.
The only other things I’d be waiting on would be true 60-120p 3D with passive/no glasses and 4K+ resolution. But that is low on the list as I don’t think I’d really make use of them.
NetFlix is to have 4K streaming in a few years but I think Blu-Ray probably looks better now than their 4K streaming will.
