First I am surprised you were happy with the Pearl (VW50) on gaming. Though a great projector, the SXRD technology (and LCD) tend to have slower panels which for fast paced viewing, such as many games, often people were bothered by it.
That being said, the newer generations are better in that regard. DLP, though you dislike, is actually one of the best in terms of speed. Since you were fine with the Sony VW50, I'd say any of the ones you listed would be a good step up.
A couple notes on 3D. First, yes ALL 3D displays lose light output in that mode. It is NOT a function of the projector itself changing, rather how 3D works. The glasses themselves cut the light that actually hits your eyes substantially (easy way to demonstrate is go to a store with a 3D, turn on 3D, but don't put on the glasses...will not change the brightness you see).
The other thing with 3D is it is more demanding all around. Your computer often needs more horsepower (especially the video card) and the display is the same way.
Just a few things to think about.
