The software giant's Netherlands team appears to have let the cat out of the bag with its own post.
According to PCR, a translated version of the Dutch language blog appeared unofficial fansite Windows8beta.com.
It read: "It will take about two years before Windows 8 [is] on the market."
However, the blog now appears to have been taken down.
Microsoft last week announced its intention to take on Steam with a revamped Games For Windows platform.
