I wish I had a crystal ball...do you think that the next generation of JVC projectors will actually have 4K and Dolby vision?
I think native 4K is very likely, but only if they can remain under 10K as JVC never really offered anything above that (in the consumer PJ market). Laser could be there as well, I think it will be one or the other, unlikely to be both laser and native 4K the same year.
If it's possible to implement DV on projectors - which I'm not sure it is due to the many variables like screen size, lamp mode, iris settings which impact on peak brightness - then I hope they will implement it. Hopefully the UHD Alliance will come up with a UHD Premium spec for projectors, which might help getting something closer to a HDR standard for consumer projectors (which have been complerely ignored up to now).
You should be asking this question in the main JVC thread though, as it has doesn't have much to do with the Autocal.
