Mark,
The calculation can be done from the other side:
The full sensor size for K-1 in pixels is 7360 x 4912.
The physical size is 35.90mm x 24.00mm.
35.9 mm = 1.413386 inches.
7360/1.413386 = 5207 dpi.
That's more than 4000 dpi for the same size of the slide film.
Or, in yet a different way, the size of the image scanned from the
36mm slide @ 4000 dpi ~= 5654 (5670, if you take 36 mm) x 3780 pixels.
For the larger size, 6x7, the size is 56mm x 67mm
@ 4000 dpi = 8818 x 10551 pixels. That's definitely more than 7360 x
4912.
But, as you said, - not everybody might need that.

Interesting - I wonder how pixel shift would work with a setup like that.
For 35mm slide film that would probably be an ideal solution. A 4000dpi
scan creates a ~22 megapixel file, smaller than a K3's. Converting color
negs might be a challenge.
For medium format scans the file sized would still be somewhat small
compared to a scanner. A 6x7 scanned at 4000 dpi comes in at around 100
megapixels. But if there is no need for such a huge file it would probably
still be fine.
