Vudu has upgraded their remaining James Bond titles to UHD and all are on sale, 2 for $14.99
They also have some great prices on TV complete series: How I Met Your Mother, 24 & Sons of Anarchy $29.99 each.
Universal is the best at including both cuts on the 4k disc. Robin Hood, Straight Outta Compton, American Gangster, Fast & Furious 5-7 all have both cuts on the disc. Their only miss in my collection is Fate of the Furious extended cut was digital only. Going by this pic of the back I'll say...
As Jeff said yes it did port over as UHD. Vudu still doesn't have the UHD version of FoD. Hopefully it's coming soon. Backdraft which came out the week before FoD on disc was upgraded to UHD on Vudu on 6/7.
