Where are you supposed to get this 4K content? they mostly don't even broadcast in 1080p yet but we got 4K now? is that supposed to fit on a Blu-Ray or is there gonna be some new type disc for it? if we're talking 4 times the resolution of 1080p seems like that's just gonna chew through the gigabytes pretty quick. our ISPs mostly have bandwidth caps now so where is one supposed to get 4K content that makes buying these TVs even worth it?
