Seems like OLED & 4K got most of the press with Sony and LG competing in both those categories. It is interesting that Sony and Panasonic announced a partnership to develop OLED Panels together. Hopefully this means prices will be lower on these new sets that come out from both Sony and Panasonic in the future.
Other than that seems like the usual small improvements in picture quality from the major players, Sony, LG, Samsung and Sharp. Of course the new Smart features appeal to some, not so much myself.
