In my opinion, 100%.
But there's different flavours of active and passive.
The "active" that most people more readily identify is the standard frame switching, with active glasses. lots of flicker, and low frame rates. Gives me a headache.
But there are also the "active/Passive" systems in use at most movie theaters, where there is a single projector, with a phase-switching device mounted, and the users wear passive glasses. Most folks don't realize the flicker and frame rate limitations inherent in this design, even tho it can perform better, potentially, than their home TV.
For the full passive system, with two projectors, discussed here, the benefits are more light output, higher frame rates, smoother 3D, and passive glasses.
I think it's hard for most people to grasp the difference between what they see on my setup, versus what they have been subjected to in the theater, until they actually witness it for themselves.
My preference to date, has been for using the polarized systems, simply because they made it easy to acheive the end result without additional processing hardware. I bought an entire set of Dolby/Infitec lenses with 20 pairs of glasses, and the first time I tested it out, realized that I had made a mistake. Wasn't happy with it at all.
But this Omega system being discussed appears to me to be a much better system than the Infitec, so I'll be checking it out also.
Regardless of how the light is output, though, the big advantages of going to two projector route is constant light output, without phase switching, or frame switching, no flickering, higher frame rates, and the ability to do frame interpolation.
Regardless of how one feels about frame interpolation on normal 2D 24p movies, one has to throw all your previous knowledge, or biases out the window, when it comes to 3D.
Your brain is very clever, when it comes to 3D, and it knows something is very wrong when the frame rates are low and juddery in 3D.
Frame interpolation, and smooth frame rates are essential to getting the best and most immersive 3D experience. There is NO "soap opera" effect in play on 3D content. Watching Avatar only one time, in full frame interpolation, will blow your mind.
