I'd say that's probably one of the main reasons to have Gigabit. Even with Netflix's less then perfect HD, I use about 100GB of bandwidth a month with Netflix. If they doubled the quality (which I'm sure 25Mbit down would support), I'd be hitting bandwidth caps with Time Warner.
With .265 being standardised soon it should be possible to do 4k at around 20mb/s at least if I remember my math right.
