Microsoft Office, which debuted on the iPhone in June of last year, is finally expected to come to the iPad next week via Satya Nadella's first press event as CEO of Microsoft. Members of the media have been receiving invites to this supposedly mobile-first and cloud-first press conference, and according to sources for The Verge the event will mark many major announcements - with Office coming to Apple's tablet being only one.
The iPad version of Microsoft Office is expected to be much like the iPhone version, and as such will require a subscription to Microsoft's Office 365 service to be able to edit documents. Document types supported in this mobile version are the same as the iPhone version; you'll be able to edit within the Word, Excel, and PowerPoint apps.
We'll be sure to let you know here at 148Apps when the app is officially announced.
