Windows 7hasn't hit the stores yet, but there already are speculations about Windows 8. A roadmap reveals that Microsoft plans the release for 2012.
A roadmap of the Italian Microsoft subsidiary reveals that the software company plans the release of Windows 8 for the year 2012. This apparently confirms that Microsoft wants to release a new operating system very two to three years.
Only recently Microsoft finalized the RTM of windows 7. Planning for Windows 8 is taking up speed, says the Blog that published the roadmap. Furthermore it seems that Microsoft sticks to the tactics of planning release dates on a conservative basis. Chief of development Steven Sinofsky introduced this with windows 7 in order to prevent such a disaster as it happened with Windows Vista. Therefore Microsoft might target an earlier release date internally.
