Contrary to you, I hope they continue to sale the CFV-50c as it is, or with a minor improvements, like the new screen. The lenses are not up to the challenge (as far as I know)
I agree that it would not nice if they remove the €8K CFV-50c product and replace it with a €20k CFV-100c. Unfortunately the history tells us that there can only be one CFV back at a time, so indeed sounds like a good idea to stay on the 50 for awhile. If they do introduce a CFV-100c I hope they make it in parallel, or make it the only product for the reason it was before -- the price is so low that no other product fits below it.
But anyway, regarding the lens not being up to the challenge is because people are crazy about pixel peeping. When will people realize that aliased false-color jagged pixels are not the utmost example of image quality?
The V lenses render as great as they ever did, and with a larger sensor rendering aspects will improve regardless resolution, but yes they will be somewhat soft on peeping, especially in the corners.
Unfortunately the pixel peep sickness is so common in customers so you're still probably right, the V lenses aren't really sharp enough from a marketing perspective...
