An Android release may have to wait until PC, Mac, and Windows Phone updates are finished
An official Microsoft Office app release is one of those things that seems to get further away as time goes on. The last notable rumor pegged Microsoft's suite of apps coming to Android in March of 2013. The newest rumor, an alleged roadmap being reported by ZDNet, lists Office for Android coming in 'Gemini Wave 2.0,' or October 2014. The first two 'Gemini Waves' show Office updates for Windows Blue, Office for Mac, Office RT, and Windows Phone. Once the developers get these out of the way, Android and iOS are supposed to be next in line to receive Office apps.
According to this roadmap, Office just isn't in the stars for Android as a 2013 release. Even if this information is correct, it wouldn't be surprising to see the release pushed back further, and Windows Phone keeping an exclusive on Microsoft Office for the foreseeable future. Luckily Google has been preparing for such a scenario, with its acquisition of Quickoffice to beef up its own apps product suite. The free copies of Quickoffice bundled in Google devices and given to Google Apps for Business users will have to do while the wait for Office for Android continues.
