If there is a widely accepted standard, there is a guaranteed customer base. 4K is the next logical plateau since it is gaining traction as the next broadcast standard (although NHK is pushing for 8K!).
There are only two suppliers of flat panels, Samsung and Sharp (and Sharp isn't looking good financially). If you ask them to make a common, but not wildly common resolution, it will cost much more.
In two years, you will be able to buy a 4K monitor for the same price as a 1080p screen, and all new video cards will support it.
Until, when I look at a video game on my screen and look at a live action TV show and can't tell the difference, there is room for improvement. Perhaps the improvement needs to come from the game developers, but there is still room and I do not believe we have hit the pinacle of GPU performance.
By the way, 4K will replace 1080p very soon, so the article is doubly moot.
