IMAX digital projection

IMAX slowly adopting digital projection.
I'm curious if anyone has more details on these new systems. I assume a 6 to 8K resolution would be needed?

That's just a crude comparison. Personally, what I would like is for something like the Sony 4K projector except doubled in both directions, as if you stacked four 4K projectors together -- so that would be 8K projection.
Now how they are going to store and playback 8K files in real time, beats me.

35mm print project is more closely related to 2k. I didn't realize that. What would anamorphic projection be?
Well, it's a crude comparison, not a scientific statement. You hear all sorts of abysmal numbers for the number of lines of resolution in print projection. To my eyes, 2K digital projection is similar to good 35mm answer print print projection in terms of sharpness.
Anamorphic print projection would also be 2K in theory (it's the same width of print area as 1.85, just expanded optically to wider dimensions) but less grainy than 1.85. Although in a sense, it is being enlarged less to fill the same height screen, so it could be considered to have more resolution vertically, and thus overall, but not horizontally, as 1.85.
I don't know if the DCI masters for anamorphic movies screened digitally are squeezed for anamorphic projection or just shorter vertically.
