Pixel orbiter was missing in the EU 2010 models (I own a VT20), are you saying that it's finally there also in the EU sets? Nice!
I can confirm that retention is an issue in the VT20 models, and crosstalk is very noticeable in PS3 3D gaming.
How much better are retention and crosstalk in this GT30?
It would be useful to see some comparative shots (even faking crosstalk, just to understand how much it's improved).
Yes, there's a pixel orbiter as well as some test patterns in the advanced menu
I think that crosstalk in games also has to do with the actual execution of the games from game developers. I have seen some games with almost zero crosstalk and some with a lot. Crosstalk should be pretty constant from the TV but there's also a higher degree of crosstalk in very dark games with high contrast images.
Crosstalk is not much better - probably on the same level.
Retention is reduced but not gone. Compared to the VT20 (that has too much retention in my opinion), GT30 definately does a better job here.
I will try to take some more pictures but unfortunately I have to return the TV soon.
