The major names you listed and the studios are loathe to have an unencumbered HD or 4K content system. I can't guess how long you've been around but 4K should be another minefield with more mines than HD (AKA BluRay.)
I've been researching 4K streaming media players, and located a new contender at the CES- the Nuvola NP-1 4K Ultra HD Streaming Media Player from Nanotech Entertainment.
It can stream 4K from a channel without the need to download content before playback. It can stream 4K content from pre-installed apps including Netflix, Hulu Plus, Amazon Prime, YouTube 4K, and Nanotech's own 'UltraFlix' 4K Ultra HD channel...we'll see.
They say it will link with any UHDTV with an HDMI port. It is suppose to be able to decode a variety of video formats and resolutions including 4K Ultra HD, HD, SD, and 3-D movies as well as playing state-of-the-art 3-D video games. Cost? $299.
Anybody know of any competitors that can do all this for $299? Would like to know my options before I buy.
I saw the Sony, but it doesn't stream-it downloads. Plus, it was over $600. and doesn't even properly connect with all of Sony's 4K tvs! Weird.
