Yes I hope your right about 5 days that will be huge! I think we (myself included) are so fixated on UF getting on Sony/Hisense/Samsung that we forget that the Roku's and Amazon 4k Fire boxes bring UF to anyone with a 4k tv -- doesnt matter what brand! Im a Roku 3 user myself and will def be getting Roku 4 after my 4k tv purchase as the interface and additional features are better with Roku than what a tv itself offers and the audio quality and options are much better not needing to use an ARC or optical out, I like everything going through my receiver. I was trying to find a way to ask Amazon support about UF on the upcoming Amazon 4k Fire but couldnt find a way to do that.
