It's all a silly misunderstanding, we tell you. Microsoft has been holding fast to its "three years" development time frame for Windows 7 since forever, the problem is that it's never been clear when that three year period started. Well wonder no longer, Microsoft has finally officially confirmed that the three years started at Windows Vista's general availability release, which was January 30th, 2007.
Obviously that doesn't mean will have Windows 7 on midnight of January 30th, 2010, but it does mean we can look forward to sometime within that year for a release. Microsoft plans to give an exact release date only once Windows 7 "meets its quality bar for release." Sounds like a good metric to go by, if you ask us.
