What I've seen, (search for Dr. Soniera's critique of Apples use of the term "retina display") is the number is right around 100 pixels/degree. So at a typical viewing distance of three screen heights, that's about 18.9 degrees * 100 = 1890 pixels, or almost UHD/2160p/4K. Certainly much more than 1080p. At 2 picture heights it's more like 2800, at 4 picture heights it's about 1425 lines.
My personal opinion about the cine 1000 is that it looks like a quite attractive projector. However, the VW1000 was somewhat of a game changer. If you look at B stock VW1000, it's not that much more expensive than this projector, and from what I've read, the VW1000 should have superior image quality, even with 1080p content.
It is quite a bit more than the post-CEDIA special pricing though.
I think that's the key reason why the interest in the cine 1000 might not be as high as one might have expected. Personally, I'm a bit short of money at the moment, but I'm kinda waiting for my ultimate dream machine, which would be something like the VW1000 with an LED/laser light source. Maybe we'll get that next year, we'll have to wait and see...
I wonder if that Optoma HD90/HD91 will have that special "LED look" that so many rave about? Reason I ask is I have a Vivitek Qumi, which uses LEDs but I've not been very impressed with it (maybe I should hook it up to my Radiance and calibrate it and give it a fair shake.
