Hey, nice reply...
But, I want to add, Panasonic VT50, and many other PDPs, are 10-bit.
Anyway, who really needs 10-bit? Who can see it? Until yesterday you needed Quaddro graphics and professional monitor to see 10-bit colour. It is meant for mastering.
I do know, however, that people with surplus of time want to have all the technology in their homes just for fun, but nobody will see improvements!
I watch from 3.5m (about 12feet) my VT50, and my player is Oppo105. There is no way I could see improvement from this distance... Actually, after a few years of watching this combo, I am still astound every time I play a movie! And am professional video artist (3D, but I do know a thing or two about picture quality). Also, I seriously doubt that any TV, except last model of Panny (studio master panel), could have better colours.
Not that I say it is impossible (but maybe it's not!), but simply marketing has gone too much into HDR and 8K talk, and neither are needed to have perfect picture.
Lastly, pixel count is matter of relation to the size of the screen. 4K was for theaters! So, from 65, and above to be 4K, maybe. Just maybe. And, you don't buy 65 to have bigger picture, but because you are sitting further away? Don't you?
... But even the sound of 8K makes me sick!
And to answer your question:
If I fall for it, it will be a flat, Panasonic, hopefully not larger than 55"... But that all makes me wonder why are we hurling into all this mumbo jumbo resolutions and colours?
We need new TV, player, discs, bigger servers, faster Internet, better cables, new speakers, eyes, ears... And for what? For 3% improvement?
Not technical, but perceptual improvement! Maybe it's even less.
