After seeing the picture of the first owner's screen of the 857, I called Sharp this morning to have them send me another 844 for my replacement. I just don't see how the new edge lit (inferior technology), even with the newer features will outweigh the full array lit 844.
I don't have a timeframe, I am due a replacement direcctly from Sharp. I have been putting it off since November. This will be my second replacement from Sharp. Last time I spoke, I told them I may want to wait until the 2013 models. So I probably dont wont to wait too long as Sharp (not the stores) may run out of 844's
This site is showing 20 in stock of the new 80" LCLE857U, stats say it is backlit, doesn'r say if full array or edge
