Well, guess what, I finally came around to order a 65HX923 today, which hopefully will be delivered this week. With IFA 2012 now in the 30 day window it felt safe even though the HX95X might be released then. If it turns out Sony will release a TV twice as good for half the price, I still have a chance to upgrade
I must admit it was a tough choice between this one and the VT50, made even harder by the fact that this is a 2011 model, which doesn't make it any less good, but still. Never the less, it was hard to ignore the extra "pop" this has in the image compared to the VT50, besides not having to worry about IR, burn in, power consumption, heat etc. In the end, I think it is hard to go wrong with either of the sets to be honest.
