It clear Microsoft intends to replace VBA with JavaScript that will run both in desktop Office and Office Online - we have it already with "Office Apps", but Office Apps are sandboxed pretty bad and have zero access to COM and legacy Office components. Assuming Microsoft eventually brings JS-in-Office to feature-parity with VBA then they can kill off the old editor.

It will take many years before they can do that. First because they haven't provided an alternative yet (javascript is used to create addins, not for users to create scripts or make new functions available). Second because you have millions of business processes that rely on VBA. So as far as I can tell the transition hasn't even started.
