Yeah I hope you're right about a bit of a renaissance for physical media. I've always had a predilection for collecting things and I love movies so it was an easy sell for me lol.
We'll see what happens, it's hard to see the big picture without sales numbers and costs; hopefully the studios continue to support it and we can carve out a little niche.. I don't think it will ever get back to the glory days where DVD releases were on par with the cinema release in terms of $$ (according to Matt Damon on that Hot Wings youtube video - check it out). It does seem like we're getting a lot of re-releases on 4K of older stuff which is fantastic.. and yes +1 for more concert films on 4K!
I have cut back my streaming services; there is too many and they're getting pricey..
