Promised iOS and Android versions of Office won't launch until the fall of 2014, according to a leaked roadmap obtained by CNet. The document describes a project called "Gemini," said to be Microsoft's plan to incorporate the Metro user interface into Office. The first "wave" in Gemini is expected to be an October 2013 update of the core apps -- Word, Excel, PowerPoint and OneNote -- that will run on mobile versions of Windows 8 and Windows RT. The software will allegedly supplement the desktop Windows suite, instead of replacing it.
