Am I EVER happy I was pointed in the direction of these forums by a friend.
I was literally 12 hours away from going and buying a hx 920 here in Hong Kong 'on sale' for 6,800 usd (our prices are obviously not comperable to the US) down from list of 8,000

. For this market in that size panel, its the most expensive one followed by the Panasonic vt50 at 6,400 usd.
Funnily enough, the Sony Hong Kong website doesn't even mention anything about a hx950 (I gather the xx9 demarkation is for the US version). There is only the hx920 on that website.
Regardless, I am not going to be buying an imminently 'old' panel - I would pay the premium for the latest and greatest as I would hope to be getting 7 years out of it like my current set which is now going to be relegated to the den.
To be clear, the 950 (or 959 in US) sounds like its a 'full' led panel - smart backlit, whatever you want to call it; not an edgelit? I was quite impressed with the picture quality of the 929 but man would I have been po'd if I saw a 950 in the shops within a month of buying it.
