As for 4k TV's, unless you're buying a REALLY REALLY REALLY huge tv, you probably don't have the eyesight to actually take advantage of the difference. And by huge, I mean so big it won't fit in most people's houses. Like, movie theater sized screen big.

THIS.

We're talking about the format that replaced/is replacing film in theaters. Having that much resolution at home seems like overkill.

HOWEVER, as close as I sit to my TV to play Xbox, I might benefit from 4k if they ever made console games at that resolution.
