had the 46D8000 nearly a week now and here's my thoughts. The good and no so good!
Picture motion is excellent - very smooth picture processing. (10 times better than the 46C8000 i used to have - was way too juddery).
Picture quality stunning, much better black levels and easier on the eye than C8000. Handles SD & HD very well.
Design/Sound - great looking cool tv and very good sound.
PC Connectivity/Network - Fully loaded altho a qwerty would help.
3D - Watched Despicable me - very good experience.
The not so good
Different names for it but - Clouding/Blooming/backlight bleed is noticable on my set but ONLY under these conditions. Watching at night in a fully dark room/curtains closed/ credit scenes with text on black background/deep space or night sky scenes with stars. Clouding was around evident in many parts of the screen. Bluray Stardust is a good test or Descent.
I'm just reporting on my own experience and no doubt others will report no clouding/blooming issues and that my set might be at fault. Although I would suggest that users create the conditions above and try films out to test there own sets. Do a few tests with a few different films as some might not show the problem but others may show it. I paused the bluray on affected night sky scenes and tinkered with the following settings/backlight/brightness/black tone/shadow. Clouding was reduced a little but not fully. Swithing on a bedside lamp or main light instantly cures the clouding and night skys looked inky black.
All in all for me its an amazing tv although the clouding under specific conditions mentioned above does niggle me.
ps - Set used in the UK
