You need to go to see one in person for yourself. I got a look at one of their 55" LEDs (not positive which model) in a Magnolia a few months ago, and the look inexplicably amazing, edge-lit or not. The motion looked very natural with no noticeable artifacting. I didn't spend a whole lot of time with it, but it was hard to believe I wasn't watching a plasma.
