Good news there will be new and more training provided on Google Analytics: given the rapid pace and number of changes to the product, help across the board from basic to advanced is a good idea.
Probably buried deep in the small print but surfacing upon log out is an interesting statement:
Google is not affiliated with the contents of Google Analytics Academy or its owners. If you sign in, Google will share your email address with Google Analytics Academy, but not your password or any other personal information.
So the new training has been out-sourced or contracted out, and perhaps isn’t provided by core Google services.
