Next step for TV

[Mikeblu]

So what do you think the next step in HD is 2K,4k,UHD ect
Well this is basicially the thread for anything like that.
Allow me to explain the obvious choises;
2K - about 2000x1300
4K - about 4000x2000
UHD - about 7000x4000
*I will edit with the proper defs once I've got them
or this is my idea stacking for a more 3D look here is a pic;

basicly you stack multiple HD, 4K tvs ect on to each other yet slightly spaced out to create a fake 3D effect sort of like the titles of mock the week. This way you can get high quality video in 3D while all attemts at holographic 3D are either failing or are unbearably low qaulity.

Disks
which disc do you think is next or DD will take over eventually any opinions on this.
The main discs in development are;
HVD - 3.5TB possible disc
PCD - 50TB possible disc, lots of issues
LS-R - 1TB possible disc
DD - bandwith issues
and they are a couple more.

I am expecting a format war between LS-R and HVD with LS-R being the first to come out but HVD being highly superior.

So your thoughts?
