I've heard that Copal is going to stop making their popular mechanical shutters (not profitable enough I suppose, their core business is in other areas these days), the last production run towards the end of the year with stock probably lasting for a year or so, so there's no immediate shortage. Haven't been able to get an official announcement of it yet though. If someone has a link please provide.
If nothing is made to replace them I guess we will have to live with the slow, expensive and bulky electronic shutters designed for studio use. Does not feel that good for me using the camera in the field. I prefer a mechanical shutter, and I think it is considerably more popular in the sales figures too but I'm not sure.
While a good electronic shutter alternative can be made I suppose, I think some of the charm of the tech camera is lost when it's no longer all-mechanical, and you (probably) need a shutter control box on the side.
