Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
New Office for Mac to Come Next Spring, Office for iOS Not Arriving Until Fall 2014?
The map says a new version of Office for Mac will arrive in April 2014, while the long rumored Microsoft Office for iOS and Android will arrive next Autumn, in October 2014.
I do not know how old this purported roadmap is, but my contact indicated it was likely current as of the start of 2013. I asked Microsoft Office officials for comment on the alleged roadmap, but they declined to do so.The most recent report, from this past December, suggested that Apple and Microsoft were in negotiations over revenue share as part of Microsoft's Office 365 subscription service that launched in January. Apple wants the standard 70/30 split in revenue that is part of its developer license agreement for every developer.
Microsoft itself has leaked references to Office Mobile for iPhone, Excel for iPad, and PowerPoint for iPad, making clear that Microsoft does have iOS versions in the works.
