Ive demos epson and sony and owned the AE8000. The Epson has the least crosstalk, in fact its so good, i thought all LCD 3D projectors would be the same.... I was so wrong. Dont know what epson are doing, but their 3D performance in terms of crosstalk is almost as good as a DLP projector.
The sony comes second, and last and by far the worst is the panasonic AE8000. I dont know how they are legally allowed to sell such a 3D feature as its appalling. The crosstalk and ghosting can be so bad, that in movies far objects/backgrounds are all fuzzy and impossible to focus. This makes 3D racing games impossible to play as its just as mess.
The only reason i choose to keep my DLP HD33 instead of upgrading to the epson is because the epson has much softer focus and the input lag for gaming is not good at around 40 to 50ms.
The Sony has a beautiful sharp image, but i am not sure if i would be happy with its slight crosstalk now that im spoiled by my HD33 which has no xtalk at all.
The odd thing i am finding is some panasonic AE8000 claim they see no xtalk at all. And some HW50 owners say they see xtalk only on some scenes. This really confuses me as it mean different people see crosstalk differently, as on both AE8000 and HW50 i saw xtalk on every scene/frame.
