On my 50" V10, THX mode is the only decent mode. Every other mode is a compromise.
If the Australiasian V20's don't offer at least one mode that is equal or superior to THX on the V10's, then a VT20 will be the only superior 2010 model available in NZ when it comes to colour and grayscale accuracy.
Not only do Europe/UK get the G20, but both also have THX. I'm hoping its just a licensing cost saving choice and not a dumbing-down of the model.
