I was reading the thread here with the 12mm Heliar on the NEX-5n and the issues that plagued the M8 and M9 have been solved using a different sensor design , micro lenses and software. There is no cyan on the edges, colors are great and the image is sharp from corner to corner. The NEX-7 will be the same. I hear there is a NEX 9 full frame in the works as well. Leica is being beat at its own game for a fraction of the price! If I were them, I would try to re-establish the old Minolta partnership ASAP! Minolta is now Sony. The M10 should be like the M9 but incorperate the advances I see in the NEX 5N and NEX 7. There is no question about it. I own 2 M8 cameras and did not buy an M9 because the M8 and M9 were too close in performance. The M9 is full frame, has slightly better ISO, etc,, but that was it. The NEX 7 will be way ahead of the M9 (except full frame) in many ways (the price is almost for free when you consider what the M9 costs and what the M 10 will likely cost) and will be my next camera.
