First of all, I also don't get why people, especially developers, with common sense could be confused about the status of .NET. In particular it appears that .NET will have more easy access to OS components in Windows 8. Maybe it's because some people still think back to the role of "managed code" in the Longhorn days.
That said, I seem to remember a comment when Windows 8 was first demoed publicly by Sinofsky and, Julie Larsen, where there was a remark that made it seem like HTML 5 development had suddenly been raised to a preferred method of developing apps for Windows 8. Of course that's nonsense and anyone with common sense should be able to deduce what was meant. It does show how easily confused people get about future directions.
I'm sure Felix can track down the comment - although it's just for historical curioisity at this point.
