I am looking for the same functionality (and noticed quite a few forum posts looking for the same thing without having to go back to the server).  I have a need to build a custom url (AngularJS) and need the start and and end dates of the view after navigation has completed (or the start and end dates the user is going to see not what they currently see).

Basically, yes.  I wanted the view's start/end dates, when the view is changed, or when the arrows are used.  I checked the scheduler code, and it appeared that they are not yet set when the navigate event is triggered.  That may make sense, in case the user wants to prevent the navigation, but if there was an event for after the navigate was completed (like "navigated"), then the view would be ready at that point, so I could then get the new dates for the view.  I found an undocumented "activated" event on the view, and started to use that, but ended up going a different direction for what we were doing anyway.  I hope that helps.  I don't exactly need it anymore, but maybe it could still be a useful event.
