It may have a separate timeline but it does seem to hint at going out the door in similar order on Office as well. I think the Python in Excel stuff is still in beta but things like lambdas, regex or Office Scripts all actually work (even on the web versions) and start taking big bites out of why you'd want to look at VB. New Outlook dropped VB support even on the desktop and I don't think they plan on maintaining separate development platforms for the other apps forever.
