After the somewhat lacklustre 3D stuffs, the industry's new idea for sucking money out of consumers rebuying remastered old films is quadHD (3820x2160).
Awesome, 4x resolution of 1080p.  My question, though, is whether wee'll actually see much 'true' 2160p content...

Anyway, apparently QuadHD TVs are actually being sold in Korea, so this probably is the next thing.
However, there still isn't any QuadHD Bluray spec to my knowledge, and there aren't any QuadHD TV transmissions either, so unless the studios embrace digital distribution (as if that'll happen any time soon), it actually could be a while before the content is actually in reach.
Next gen game consoles?  Haven't heard anything on that front either.

By the way if you want to see some high def clips, there's the short free film, Sintel.  Unfortunately there doesn't seem to be a 4k encode, but if you're really interested, you could theoretically download the 94GB of PNG files (483GB if you want 48-bit colour) and make an encode yourself.
