I imagine there would be a physical media release eventually?
I reserve physical media purchases for things I’ve already seen and know I like, or perhaps something I feel I’m extremely likely to enjoy. I don’t have enough faith in any franchise beginning with “Star” at this point to blind-buy media.
Do you blind buy any media though? Not many do.
I used to quite frequently after I gave up on theaters (too expensive, crowded, and noisy) and stopped caring about being current, but once 4K became more prevalent, I pretty much stopped buying Blu-rays because I don’t have a 4K display yet and didn’t want to waste money on old media I’d probably replace (or jump into 4K early and end up replacing those because early releases on DVD and Blu-ray were often shit).
I’ve found 1080p streaming, while not as good as Blu-ray, to be adequate in the meantime, especially since I watch more TV than movies these days and care a bit less about A/V quality for TV shows.
4K is the niche within a niche though. And now we have more questionable color decisions being made and seldom an original audio mix in sight. I’ve read not every 4k display has all the new color tech, and yet another format has been unleashed on us where all the finer specs weren’t finalized. Yay progress!
I’d say if you buy a 2018 4K display with Dolby Vision and HDR10+ (either out of the box or promised in a future firmware upgrade), you’re pretty much covered. There are some other benefits to HDMI 2.1 like variable refresh rate, but that applies mostly to gamers.
I’ll probably cave on Black Friday and make the jump. I like to sit pretty close to the TV, and while my Pioneer plasma has held up remarkably well, I can see pixel structure and occasional aliasing. Even 1080p sources see some benefits in that regard when upscaled to 4K.
