P1 will sell the shutters quite expensively and delay it until XT tapers off. Latest I heard is an optimistic Q4. Means sometime in 21 for a substantial mark-up ... imagine lens prices where alpa, rodie and p1 get a cut ...Agreed, the XT has some nice features but some of them I could have with my Arca system once the X shutter is available for other systems. My hope is that the x-shutter will be useable without the IQ4-150 via an app or control module (Silex!) but I’m not holding my breath.
