For anyone who is curious about what Microsoft has planned for its Windows Phone, here is a leaked roadmap that reveals some details about the future, up to date as of October 2011.

The roadmap lays the foundation with the release of the Windows Phone 7 in the fourth quarter of 2010 as a high-end and differentiated product followed by Mango also in the fourth quarter of 2011 that offers new features, languages and countries.

The beginning of 2012 will see the release of Tango that focusses on enabling Windows Phone 7 on low-end handsets at the best prices. Finally, the fourth quarter of 2012 will see the Apollo, when Microsoft finally expects volume to increase, enable the release of superphones and concentrate on users’ business needs.
