One thing to note, our engineering focus is Office web add-ins – web add-ins work across devices and platforms, and developers enjoy a modern web development experience. In addition to the improvements discussed there, including connecting the applications you build to the data and services available in Office 365 and creating add-ins that connect to third-party services, we continue to support developers working in VBA by adding new objects and members to the VBA object model across nearly all the Office applications. Recently, we shared an overview of the new extensibility capabilities available for developers as part of the new Office 2016.
