Still hoping to hear something interesting.
I want to share an interesting blog that I found in the mean time. I was looking for hints of a Samsung NX adapter for Leica M lenses and this post clearly explained to me why one won't be forthcoming: http://petavoxel.wordpress.com/2010/01/16/ltm-on-nx10/. The article will matter to those who were hoping for such adapters, like me, but the blog as a whole may be of wider interest.
So far the group of photographers that wants to use M lenses on other cameras hasn't been very lucky. The m4/3 sensors have a crippling focal-length multiplier in my opinion and deliver mushy corners with Leica wide-angle lenses. The only competitor to show up (the NX10) won't be getting an adapter due to mechanical constraints that could have been avoided with a wider throat. Where's that Sony/Zeiss DRF when you want it...
