When reviewing an on-line ad for Best Buy, I came across a Samsung 50" model UN50ES6900. Samsung does list this model on their website (it appears it is only offered in a 50" screen size). However, I can't find anyone on the AVS Forum who has written anything about this model. I guess it fits in somewhere between the ES6500 series and the ES7100 series, but I would like to know what the differences are between these models. Any help would be appreciated.
