regarding the LG... I was reading lots of reports direct from CES from folks who were attending the demonstration. It was posted then (I think some threads at AVS) that it was a silver screen, circular-polarized, and single-chassis with dual-light-engine SXRD with single lens output. The only way to get polarization that way would be to have the filters in the light path inside the box before the light from the 2 engines is combined for single output via single lens, so that last part is my own extrapolation (but 99% sure to be correct given everything else).
I provided two examples of 3D projectors that use passive-polarized goggles: one has two internal light engines (LG) and one does not (Real3D theatrical projectors), so there's no "limitation" fundamentally when we talk about a single-box projector and wanting active or passive eyewear... there are many ways to integrate 3D functionality based on the pros and cons offered by LCOS/DLP etc. that have not been fully explored.
Now, if you *do* stack two conventional 2D projectors on your own, than naturally that would limit you to passive goggles of some kind as your only real option since it would be almost impossible to try to sync the refresh of two independent machines to do sequential left/right.
But when we talk about single-box 3D projectors that are designed from the ground-up as 3D devices, the fact that they are single-box doesn't indicate anything about the technology or 3D methodology used.
1080p and lossless audio. EVERY BD should have them both.
