When the initial release of Word 2016 for Mac was released I was unable to convert WordMat for Word 2011 to the new version.
Since then Word 2016 has been significantly improved in terms of stability and features, and more importantly Microsoft has supplied contacts and documentation from the Office devolpment team in Redmond. This has removed all obstacles, and the development is now entering the final phases. Currently a prototype is being tested at my school.
The new version will be more similar to the Windows version than the Word 2011 version was. It will have exactly the same ribbon, and installation will be smooth - requiring no manual steps.
Expected release is date 1. march 2017.
