Mary Jo Foley heard that Blue is also the codename for updates to Windows Phone, Windows Server and Windows Services

Blue represents a major change in how Microsoft builds, deploys and markets software and services. To date, many Microsoft teams like Windows, Windows Live and Windows Server have been focused on delivering major platform updates every two to three years. The challenge is to get them to pivot around yearly platform updates, the first of which will hit as part of the Blue wave.

On the Windows side, the changes required to make this happen will be especially far reaching and pronounced. Instead of RTMing a new version of Windows once every three or so years, and then hoping/praying OEMs can get the final bits tested and preloaded on new hardware a few months later, Microsoft is going to try to push Blue out to users far more quickly, possibly via the Windows Store, my contact said.

There's still no word on specific new features coming to any of the Blue wave of products and services. But tweaks to the user experience, new dev-platform related bits, as well as new versions of Internet Explorer, Mail, Calendar, Bing and other integrated apps are likely to figure into the Blue picture, my source said. Blue will include some kernel and driver-level updates which could help with battery life and overall performance, according to my source, but backward compatibility with Windows 8 and Windows Phone 8 seem to be a priority.
