I agree with that, I have the M series 55" and there is light bloom all over the place, you can distinctly see the 16 zones. I'm surprised you didn't go with the E series 47" to hold you over, it has passive 3d, VIA, and a really great picture too. Sometimes i wish i had stuck with that set instead of selling it for the 55", normal LCD seems better than edge lit in my experience, the blacks may be deeper but the blooming is disctacting and if you turn dimming off you see the clouding and edge bleed. The new Westinghouse sets look great too so I'm sure you'll be happy!
