I'm excited for this thing. It sounds really promising and I'm hoping that devs will simply ship a game with all the UHD 4K assets on disk and during install, the system will know if it's an XBONE to grab the regular installer files, textures, etc and if it's a Scorpio, to install the higher res assets and then when launching the game it will have either an XBONE graphics config preset it loads or a Scorpio preset that has values like view distance, AA, etc all turned up higher.
Could/Should be a nice and seamless thing.
