There's another non-story over at Ars Technica about Windows 8, supposedly, though if you read this post you'll discover there isn't even an iota of new information, so it's unclear what the point is. But some of it is just plain wrong. Example: Microsoft isn't doing the major/minor version stuff anymore. Windows 8 will simply be the next version of Windows, and as with the Vista-to-7 delta, all subsequent Windows (client and server) releases (including Windows 8) will be spaced three years apart.
But you'd know that if you listened to my podcast. :)
