IMHO within a decade 6-8K will be the standard for theatrical. Beyond that, 
you'd need to be projecting 180 degree plus immersive to make much use of the 
extra pixels.

It's hard to do now, but obviously since computing resources are always 
getting cheaper and faster, there will come a point when 6-8K is no worse than HD 
is today. Consider that a decade ago, SD was harder to work with on a computer 
than HD is now. No-one wants to anymore, but it's possible to capture 
uncompressed SD on a laptop with the standard I/O. Back then we needed a DDR to 
buffer. The proportional relationship isn't far different - 601 to 2K film is about 
the same difference as HD to 6-8K; about an order of magnitude.

I haven't done 8K yet - I'm skeptical whether one can really get an image 
improvement at the film recorder using CRT's, but we've certainly done 6K, and 4K 
is our norm. IMAX's "6K" (5.7K) is to my eyes actually worse than their 4K.
