Just speaking for myself, I like downloading t.v. shows on my DVR. However, Microsoft's alternate fails to see how business is actually done and will at best only be attractive to people who want to buy television shows in HD. As far as films go, how do you think movies make money after the first weekend? They sell physical media once twice or more with continuous "Director's Cuts," "Special Editions," "Fifth Anniversary," etc. that capture the buyer's impulse in a bricks and mortar store for the next couple of decades.
Sure, you can have this as downloadable too, but I suspect that the compulsion to buy another version of "Hellboy" will be reduced when you and your spouse can see the other two versions floating in a 52" screen right next to each other.
