This is welcome news indeed as long as Disney doesn't resort to the fake 4K upscaling nonsense that some other studios have resorted to. So far UHD has been a disappointment given the dozen or so 4K blu-ray discs I have bought, over half of which look barely any better than the 1080p blu-ray, if at all. Since my spectacular 2013 model Sony 65" 3D TV XBR-65X900A doesn't support HDR, I was honestly and naively expecting UHD disc playback to look even better than compressed 2160p content on Netflix/Amazon/Vudu/YouTube, but to date that has rarely happened with the glut of fake 4K movies being released by the studios. It's really not a good intro for the medium in that regard. As it is, network broadcasters are looking to implement HDR before 4K, so the reliance of slapping the HDR and Dolby Atmos logos on the packaging under the fraudulent 4K Ultra HD label is just ridiculous to push a combined product package. Yes, I understand that most CG is still rendered at 2K due to time and cost constraints, and that actors don't want you to be able to count their facial hairs, but about half of the 4K blu-ray discs released to date are either not true 4K at all or else have blended elements depending on the scene.
Having said that, I will be buying GotG 2 on 3D blu-ray, as I'll take the sheer dimensional beauty of 3D over 4K every time, although I would love to have both at once. (This would require an 8K passive 3D TV, which does not exist yet on the market.) The unforgivable idiocy of some studios to discontinue 3D disc releases in the United States is at least still frequently overcome with a little patience and simply ordering them from Amazon UK, as I continue to do.
As for the 3D blu-ray releases of the Star Wars films The Force Awakens and Rogue One, I was elated to be able to buy them stateside when they came out and had no major gripes with the transfer. Of course, we can all dream that someday all action films will have the pristine native 3D quality of Avatar, but until then, the significant improvements in post-production 3D conversion over the past five years will have to do. I'm still loving my 3D TV!!!
