Actually a nuvola player for half of the Sony has to be other than vapor ware to do a fair comparison with Sony's, similar to beta RED regardless that is twice-plus Sony's price. Only then one can evaluate content availability, compelling content type, and image quality.
Regarding Sony''s 600 soon to be available 4K projector the price is not $10k, add another half, and still is a decent price considering that will offer true 4K chip/engine, no e-shift, and 1700 lumens compared to my 1000 4k projector with 2000 lumens ($25k MSRP), which is a torch and I typically use the dynamic iris in limited because of the potent light output.
1700 lumens should be more than enough for non-huge HT screens. Add another $1000 for the player/tablet offered by Sony and it is a very good deal considering the individual prices of those two.
Sony is upgrading my 1000 projector to the new 1100 model, with a technician at home, HDMI 2, HDCP 2.2, a 4K player, a tablet, and a new lamp (approx $700 MSRP) all for an estimated price of $2500 that dealers will set depending of the installation.
Counting out $185k Meridian 4K projector, no reasonable-price 4K projectors are available other than the above three, actually only mine until November, all from Sony, JVC is e-shift and does not qualify for 4K UHD label.
Regarding reviewing of 4K content, although not from the FMP (it's precursor server did not recognize my projector early this year) I reviewed the 4K content from the Sony server used for shows like CES, some of the clips were from the same movies of the FMP, including the Timescapes documentary at full length, my overall impression with a 130-inch CinemaScope screen was that it was a mix bag of image quality mainly due to the choice of demo content.
I will review the FMP soon, and also the RED and the Nuvola, if they ever become available.
