Have you actually looked at it properly? The pixels are tiny for the screen size as a result there is a lot of dead black space between the pixels I would guess 30% of the display is dead. It is really blocky and you are promoting it for picture quality which in my opinion is way worse than 80% of the TV's out there. I own a 51d550 by the way and have gone in to buy the 60inch as I love my 50inch full of joy for my new plasma only to be totally floored by how poor it is.
Plasma has superior picture quality and motion handling.
It is not superior just for sport. Overall, it is the best.
The only area where LCD is better, is for PC use or use where there are excessive static images. Don't worry about it though. LCD is also brighter, and better for bright rooms.
Gotta side with Postman on this one... as mentioned earlier, my 64" F8500 plasma recently died and Samsung gave me the 65HU8700 curved UHD screen as a replacement. (figured it was a score, since the R34k 15mth old screen was replaced with a R47k new unit!)
In MANY respects, especially motion, sport and viewing angles, the plasma was better.
The UHD screen obviously looks fantastic with UHD material, but with 1080i DStv and 1080p media the picture only looks as good as the plasma if viewed within a 20 degree angle, anything past that point and the picture looks washed out.
The blacks on this LED are impressive, closest I've ever seen to plasma, and this is the best LED I've ever seen, but sport is still better on the plasma. The new screen has a nice fast processor, everything is quicker in the menus and the remote is much better.
