So, did I get that right? You get the Blu-ray for free if you buy the 4K version?
I don’t think I’ve seen a 4K release without a BD. Which is why my most recent buy that was Wonder Woman, I bought in 4K even though I don’t have a player yet. Unfortunately those discs cost 50% more new and don’t come on sale almost ever that I’ve seen, while you can get BDs for 5-10 euros 6 months after their release.
