Well, I have the LG 65LW6500 and it's fantastic. Also, I can't stand active shutter. I can see the flicker and I see a dimming effect whenever I move my head (even if I move just small amounts). I sit 10 - 12' from the tv, depending on which seat I pick. I don't see any loss of resolution and the 3d is great. Also, the 2d great, and even SD material is perfectly watchable. While the rest of my family is what I would call "normal" viewers, I've been into HT for a while and can see the stuff that the "normal" people don't (which is more of a curse than a blessing, I tell ya!).
I'm convinced that the full hd active vs partial passive, while true in theory, just doesn't hold up in practice. If it were entirely true (like the absurd Samsung Megamind picture comparison on their website, where they show the superhero with huge black lines all through the picture, while the active shutter picture is crystal clear), then yeah......but it just isn't like that in practice. Maybe older passive sets? I don't know, but the LG isn't like that at all. Combine a great picture with no dimming, flickering, sync issues, headaches, heavy glasses, batteries and expensive glasses and i have a winner. Count me in the passive > active camp.
Also, I don't work for any sort of tv or display company. I'm nowhere near this business.
Finally, to answer the original question, I think 3d will stay around this time. The TVs are becoming more prominent, blu rays are coming out and there are quite a few new video games supporting it (hello, Uncharted 3 and Ratchet & Clank!). Enough of the manufacturer exclusives, though! I'd love to get Kung Fu Panda2, but I guess I'll have to wait a year or two.
