2k is resolution for movies, 2048 X 1080,,,, its not far from HD... So HD cameras can be used to shoot movies. 4k is for IMAX stuff.

The numbers from Wikipedia seem to be fictitious. In AE the numbers for Cineon are 3656 X 2664 (for 4K). I am not getting any closer to understanding the future.

The numbers for 2k and 4k are approximate. There is no exact number because its for film scanning. 2k is 2048x1080, or 2048×1536, or 1998 x 1080.... There are other variations too. 2048X1080 is the most common resolution. ITs NOT exact, because film is not digital.
1920X1080 is HD resolution, its not 2k, but when a cam has a high display res (like the 5d) you can upres it to 2k without any problem.
4k is for IMAX movies.
Its not the future resolution, because hollywood already accepts 2k as the standard, it doesn't matter what camera companies do. RED can sell a 5k resolution camera but distribution companies will still require you to down res it to 2k resolution. Unless you are distributing IMAX movies.
