Actually,
the ABClocal article says 10
80 Hz.

eDimentional wireless shutter glasses are only $80, and I can imagine them going down as low as $30-50 in a couple of years.
If you consider the cost of sturdy, high-quality passive polarized glasses, not the cheap disposable plastic glasses which go for $5, I think the price difference is not that critical.

Basically, LCoS is a LCD-based
reflective microdisplay device (like the Digital Micromirror Device in DLP systems), as opposed to tradional
transmissive LCD with translucent pixels. Each pixel is monochrome and produces only grayscale grades, so at least 3 display engines with a beam splitter and colorized filters have been required for an arc-lamp backlighted system, just like in 3LCD transmissive technology.
LCoS has been commercialized by Sony (SXRD) and JVC (D-ILA); Sony has abandoned consumer RPTV market, but their professional 1080p and cinema-grade 4K front-projection systems all employ SXRD.

The two main benefits of LCoS are
1) pixel control logic is placed beneath the pixel, substantially increasing active pixel area compared to translucent pixels, where control logic eats 10-20% of the pixel area; this improves brightness, contrast and removes "screendoor effect"
2) better manufacturing process results in very fast pixel resonse times, less than 1 ms, allowing for less image artifacts in fast-action picture sequences (and sequential stereo, as a side effect).

In fact, it can be either 1, 2 or 3-engine, considering their "1080 Hz" figure; but I would expect them to use a cheaper 1-engine setup.
I'm assuming the following mode of operation. Fast pixel response time of LCoS microdisplayy and 3-color laser backlight allow to simultaneously project color components for each pixel, much like Digital Micromirror Devices in a DLP system, and form a single L/R frame at 60 Hz, with L/R color components separated by polarization device placed in the optical path, such as polarizing electro-optical switch, rotating polarization wheel or passive polarized screen.
This approach looks very similar to techniques described in a Real-D patent, see
Polarizing Color Wheel Coming For Home DLP Displays.
And yes,
High Definition Integration Ltd. (the full company name as it seems) has filed a couple of patents on laser RPTV devices, see
http://www.implu.com/patent_assignee/13964;" onclick="window.open(this.href);return false; one of them concerns an anti-speckle screen for laser projection,
.
Possible system configurations:
1 display engine, 3-color laser backlight, polarisation wheel or electro-optical swith: within a frame, each L/R pixel is formed by projecting RGB color components in a sequence, much like DLP system.
For 60 Hz frame stereo (3 color components x 2 frames), the refresh rate of the microdisplay is 360 Hz; a maximum of 1080 Hz allows "3x movie mode" (frame interpolation).
Possible component order sequence:
Rl Rr Gl Gr Bl Br,
Rl Gr Bl Rr Gl Br,
Rr Gr Br Rl Bl Gl, etc.
2-engine setup: each microdisplay would be coupled with a passive polarization screen and a laser backlight (or a single laser backlight with a beam splitter).
Microdisplay refresh rate at least 180 Hz, maximum of 1080 Hz allows for "6x movie mode".
Component order sequence: (Rl Rr) (Gl Gr) (Bl Br), (Rl Gr) (Bl Rr) (Gl Br), etc.
3-engine setup: each microdisplay would have its own colored laser backlight unit, with polarizing electro-optical switch in the main optical path; base microdisplay refresh rate of 120 Hz and a maximum of 1080Hz would allow a "9x movie mode" interpolation.
6 engines would constitute an ultimate setup where each display has its own polarization and color backlight, and will have no blinking at all. Sony will license it for their 4K steroscopic projectors (or they will just copy the idea and HDI, RealD or both will have to sue them
