I am not sure the person that recommended a Vizio knows and made you aware of the history of fire hazard and un-repairable cases of that brand, but if I would be you I would never leave the set unattended:http://hdguru.com/are-vizio-hdtvs-catch ... #more-4660 http://hdguru.com/vizio-disposable-hdtv ... #more-5596http://hdguru.com/disposable-tvs-vizio- ... able/5485/
Regarding 3D, I agree in that 3D content is being offered at a slower pace than expected, but a 3DTV is actually a good quality HDTV with the capability of showing 3D “as a feature”, so one should never consider it a bad investment because 3D content is not available as fast as one expected.
Check Amazon for dozens of 3D movies, although with the exceptions of Avatar, Hugo, and the feature films, most are actually documentaries and cartoon types such as Rio, Ice age, Owls, etc.
In a similar case I just ordered a 4K projector that I am planning to review and own, and would be able to show a 3D Blu-ray movie in 4K quality per eye even when the 3D movie is not in 4K, and although I am hoping to eventually buy 4K-Blu-ray discs and possibly 3D-4K-Blu-ray discs, I could not possibly demand them to be available now or in quantity just because I decided to be ahead of the curve with such feature.
Regarding your question about 3D broadcasting, the standard for 3D broadcast is being developed now as ATSC 3.0, which would include more features than 3D and is being designed not as an upgrade of the current ATSC 2.0 for HDTV but rather from scratch with a blank piece of paper approach.
I hope the standard will finally implement a 3D broadcast format using a higher and better quality compression like H.265 for the 3D content to be of much better quality than the half-resolution side-by-side or top-bottom frame compatible formats cable and satellite are using. In addition it is expected for the content to also be compatible for HDTV viewing of a 3D broadcast without having to broadcast two different versions for HDTV and 3DTV viewing.
However, you existing tuner most probably would not be abe to be firmware upgradeable by the TV manufacturer and you would need an external tuner that would convert the incoming signal to a format your TV would accept, such as full resolution frame sequential 3D (as Blu-ray).
