good stuff. After this comes out, no more need to depend on the good ol sony 4k projector.

Interesting stuff, but it's not a projector yet. We'll have to see what it looks like when it ships!

They are in develop. All things subject to change.

Sounds familiar... ;-)

Te he. Indeed. The technology looks great. I'd want to know one thing though - contrast ratio.

Interesting tech. From what I understand of it, I'd be surprised to see this working in a practical way.
1) If they are relying on the polarizer to give them the contrast ratio, I wouldn't expect it to be super-high, unless they have some new kind of polarizer.
2) It seems they are using a laser as a light source. Lasers are great for making bright spots, but lighting up an entire theatre screen at once requires power. If you thought existing projector bulbs were expensive, I'd think an equivalent-power continuous laser source would be quite a bit more.
3) Anyone playing with a laser pointer has seen the laser "speckle" effect caused by self-interference of the light beam. This effect makes any laser-projected image hard to watch, unless you make the source coherence length super-short. Maybe they've done this, I don't know.
