Leica M9. The new Leica cameras could use Sony sensors instead of Kodak sensors. If the rumor turns out to be true those cameras will be certainly expensive (there is a huge extra you have to pay for the brand). I hope Sony will make their own fulllframe mirrorless system using the same sensors and for half of the Leica price :)
As I said, it’s a new source and the rumor is rated with SR2 only (20-40% chance the rumor could be correct).
