Given the very few (and occasionally confusing) leaks around Windows 8, an update as to how things are progressing is always welcome.
In early 2011, a source of mine passed on to me what he claimed was a snapshot of the internal Windows 8 roadmap. On that roadmap snippet are a lot of alleged internal dates for Windows 8 Milestone 2, the second of what are expected to be three major internal builds of Windows 8. I showed off this roadmap during a ZDNet Webcast I did recently on Windows 8 and slates (which is available for listening as a free, on-demand file).
