Earlier rumors suggested a 22MP sensor that would be effectively 16MP when
cropped to 24x36mm.  16MP @ 24x36mm is about the same pixel density as the
DMR.  At this density a 22MP sensor could be 33x36mm, not quite square, or
about 32x37mm for 4x5 proportions (100% pure organic speculation).

Image circle requirements for the various (speculative) format, rounded to
the next highest whole mm:

36x36mm needs a 51mm diameter image circle
33x36mm or 32x37mm needs a 49mm diameter image circle

while 24x36mm needs a 44mm diameter image circle
