I have a theory that the Vizio Ultraflix app will be released somewhere around the heat death of the universe.
I'm not quite as certain about that as I am that there will never be audited financials. I'm only about 99% certain that there won't be an app or, more likely, it will exist but be unusable.
I don't think NTEK has created/bought the network of distribution and caching nodes necessary to do an actual roll-out. Their local server farm is good enough for the few dozen or whatever NP-1s they have, but that's not the same thing as thousands of them.
I do take as a given that the 60,000 NP-1s supposedly in the retail channel were never made and will never show up on store shelves.
