Ultra high definition at this point in time is crazy seeing as we dont really have still cameras that can produce 32mp images let alone motion cameras.
So forget 1-2 years try 10-15+
Somthing much nearer to date though is Quad high definition (QHD) its 3840x2160 which is exactly double the resolution of 1080p in each direction and thus 4x the number of pixels hence its name.
LCD's that can display this resolution exist and so do the cameras (just they are rare but so are 1080p cameras) the equipment was first shown a couple of years ago now.
However a transmition method is just a pipe dream for now. Infact going from a set top box to the screen is currently a headache since QHD requires around 1.4GB/s in raw data. which is more than HDMI and even dual link DVI can handle. This sort of resolution would push most modern pc graphics cards.
