better off doing that in the Home Cinema part of the forum, I'm sure a lot of people in there are interested in looking at the new Sony sets.
Also the extra 2 inches will be a lot better, I currently use a 50" panel and trust me bigger is better
Do you game at night or like to game in a dark room or watch movies with the lights off, etc? Then look into buying something like this "Antec SoundScience USB Powered HDTV Bias Lighting with 6500K Colour Temperature" ocuk sell them but I'm personally going with a competitor and a discount site.
Basically it helps prevent eye strain, connects to USB port on TV and is a nice cheap setup.
I had previously spent £25 on a really good setup but the cheap chinese PSU exploded and luckily I was in at the time and it didn't catch fire or anything.
So now I'm going with something safe and made to safety standards.
here is an old post of mine with a picture of BIAS lighting in work

it helps improve black levels too (picture quality).
i know it's another £15 on top to spend but your eyes will thank you for it if you ever use the TV at night or in darkness.
