These models that Panasonic are experimenting with are only concept models at the moment. I think this does demonstrate the interest in these kinds of headsets from the leading big name brands. Once the weight and size is reduced enough to appeal to the mainstream, and the quality and price can hit the mainstream sweet spots, I expect we could see many competing headsets appear in the market, launched from these premium brands.
The trend for dedicated VR headsets is towards smaller/lighter headsets with wireless connectivity, so gradually blurring the distinction between VR headsets and personal cinema headsets.
VR headsets will probably always be more (expensive and) demanding in terms of motion tracking, refresh rate, latency, FOV, dependancy on a high performance PC, etc - however, they will become more comfortable to wear for longer periods of time, and the resolution will catch up with the cinema headsets, and offer a comparable movie experience.
By focusing specifically on the personal movie experience, companies like Cinera can theoretically maintain their USP by keeping the unit prices below VR headsets, and providing models that are optimised specifically for watching movies/TV shows (with functionality for gaming and desktop replacement).
A headset with lenses and software optimised for VR may struggle to also provide a better movie watching experience as a device specifically optimised for that purpose. It will likely be more expensive too, so preferable for VR enthusiasts who want to watch films too, but not for people who only want to pay for the movie experience.
