Ok so ive decided i want a TV from the Panasonic G20 range. I will use the tv for movies via bluray, sport via sky+HD and gaming via 360 or PS3. My seating distance is between 6 & 7 feet from the screen. Space isnt an issue and neither is the price difference really. So what im basically trying to find out is, is my viewing distance better suited to a 46 or a 50 inch panel?
