The full frame circle has 3.17 times more area than the 2/3 rectangle of the current DMR sensor. If you use the same pixel size as the DMR for this circular sensor; you could have a 31mp sensor to use with the existing collection of R & M lenses.

If the pixels can be squeezed together more; we could have a 35mp circular sensor for all existing and future Leica 35mm lenses.

...and this would give a new meaning to the word RAW (you could crop the image for the different type's of output's that could be needed.

Or not crop at all.

And of course you could have different focusing screens with the 2/3 , 4/3 or square crop.
