Now that Autodesk has switched over to subscription licensing, there is no reason to put out a "new" version of Revit every year. No more Revit 2017, Revit 2018, Revit 2019, Revit 2020. Just Revit... Let this be the silver lining to subscription licensing, follow Photoshop's example and drop the versioning.
No more upgrading/complaining that one can't downgrade Revit files.
No more keeping 6 versions of the same program for Construction Administration.
No compatibility issues between consultants.
1/2 the IT infrastructure to keep everything updated and deployed
No more having to remember which Revit icon correlates with which year
