4K2K is definitely coming in the next 2-3 years. The main push is going to be glasses free 3D. While purist may not like 3D, it is going to be pushed hard by studios and manufactures. Studios love it because it eliminates camcorder piracy in the theaters and manufactures love it because they can sell you a new display. The movie studios would eventually generate more profits as consumers yet again replace their blu-ray or dvd movies they already own, to the new 4K format. Plus, it will be the new high end standard for PC gaming. They had 1080p sets before there was even any HD channels. You can already get the 55" Toshiba ZL2 4K set for under 10K street price and those prices will drop fast as mass production picks up. With Vizio, Samsung, and LG crushing the Japaneses on price, they have to differentiate their products. Sharp has done it by going to more profitable large 70-90" displays, at affordable prices. JVC, Toshiba and Mitsubishi may have to do it by going 4K2K.
