Microsoft Office 2016 is due to launch on 22 September. A leaked memo (thanks to Winfuture) says:
"On September 22, 2015, we'll release Office 2016 -- with updates for Word, Excel, PowerPoint, OneNote, Outlook, Skype for Business, Project, Visio, Access, and Publisher. The innovation wave continues in Q2 with the release of E5 and Skype for Business, and on-premise servers will follow.
This is the central hub for all Office 2016 Commercial readiness, training, and marketing materials. Mark this page and check back frequently, as we will be releasing new materials, weekly, to support the launch."
