There is some amazing things in here. 4K Digital means Vudu redeem most likely. 4k gets the special treatment of Atmos where the Blu-ray and I would assume the 3D Blu-ray don't get it. For the OLED folks Dolby Vision is included as well... Very nice! Can't wait to see the other 4K announcements.
Except that 4K Vudu is available on so few devices.... However, Google Play Movies and Amazon are also DMA partners and offer 4K on more devices than Vudu!
