The Verge writes an article saying that 4k is wonderful, unlike 3D, saying that 4k is what consumers want. This reporter does not understand the relationship between 4k and 3D at all and seems to think that when 4k comes along, no one will watch 3D.
Most people are unable to distinguish between 720p and 1080p on their large screen home TVs unless they have huge screens. 4k is designed, in part, to present 3D images. Most current 1080p based 3D systems either halve the resolution or halve the frames – with one half to the left eye and another half to the right eye.
A “4k” image is four times the resolution of 1080p (think 4 screens instead of one 1080p screen) and provides the quantity of information to present high quality 3D images.
3D works best when there is as much detail as possible and looks worse when downgraded. A 3D video shot on two 1080p cameras still ends up with the equivalent of 540p for the left eye and 540p for the right eye, or 960 vertical lines, or half the frames devoted to the left and half to the right eye. Either way, today’s system lose a lot of resolution – 4k fixes that too.
