Even as the HDMI consortium, being composed largely by manufacturers of home theater equipment, may not be thinking of this, I think you're absolutely right: 4K TVs are nearing, or past for many, the point of diminishing returns in terms of resolution. 8K is going to be a very tough sell next decade, but the future of VR will hinge on it. Today's 2K VR headsets are the 480i of their nascent industry. They're good enough to kickstart a revolution. But the next generation of VR, with 4K displays, will be like the jump to HD – and the eventual adoption of 8K will be much more impactful than the TV world's move from 2K to 4K.
