That is the resolution of the TV’s panel and not the source content signal (unless they cheated and plugged a PC into it). No there will not be a new native 4000x2000 HD format any time soon. Changes like that do not come from a TV manufacturer deciding to make a new TV, it comes from a collective decision by the broacast industry. For TV / video, that TV will take 1080 and up-scale it to its panel resolution. Since LCD is still not a great video technology, by making the pixels smaller they can enhace the detail, do better anti-aliasing etc… since they can use 4 small pixels to represent 1 pixel of the source signal. Or kinda like that… HD in its current formats (for broadcast) is here to stay for a while. The change to digital and HDTV with support for 1920x1080 etc… was a huge change and huge $$ cost for the entire broadcast industry from end to end. They won’t change it again soon, everyone would go bankrupt !
