I don’t have 4K equipment yet, so I’m mostly interested in the special features and if there will be anything new in there. I imagine that I might replace my Blu-ray collection with something like this in a few years, but for now it seems too expensive. Especially considering that you could get almost 4 years of Disney+ for that money, and watch the 4K versions that way.
It also seems weird to put both the 4K and HD versions in the same massive set. If you have a 4K player you don’t need the HD discs and if you don’t have one you’d only want the HD discs. This way it just makes it unnecessarily expensive and probably physically huge as well.
