Now you've changed things up just a bit I was responding to your original suggestion that Leica take the MP, add an angled crank and a red dot and sell it for $2K less than current MP prices. I don't personally think that would be a successful proposition. But a film camera that can be produced more cheaply/efficiently than the current cameras and uses less expensive materials is a different story.
We are both learning as this story moves along. In the discussion on LUF there is mention of a mythical camera made of lightweight material being tested. Originally, my feeling was they were going to keep the MA/MP body and move to an aluminum top plate but then I started to wonder, what if they moved in a direction no one was expecting? It's all conjecture but I would buy a three thousand dollar plastic M7!
