Don't forget the Sony (non-streaming) unit only work with some Sony TVs. NTEK clearly have an edge with a streaming unit that is compatible with other TV manufacturers. Obviously NTEK need to come out with the NP-1 as soon possible, and I am sure they are focussing on that (only two steps away!), but the fact they already have a commercial 4K streamer available on Amazon is impressive.
It doesn't take much imagination to figure out that the 4K studio is an even bigger deal, long term. NTEK!
