That article is dated 7/21/07. The stuff I read about Vienna was in PC magazine (I am pretty sure) a month ago (I am sure about the month ago part). It said Vienna would be 64-bit only. If vista was originally that transition, it only follows that since that failed they would try on the next OS. Interesting article, but since what I read is newer; I'll believe the newer stuff instead. I probably get accused of chronological snobbery for that though....
