The article hinges strongly on this quote, which strikes me as wrong: Windows 7 will ship in 2009, almost certainly in time for holiday PCs. Microsoft disclosed today that there would be no major architectural changes from Vista, which would greatly reduce development complications. The author probably heard "Vista applications will be able to run on their original architecture" and reported it as "Windows 7 will have the same architecture as Vista." Noises coming from Microsoft suggest Windows 7 will support "legacy" applications using virtualization so that they can run in their native environments, specifically to set Windows 7 free to do things without the strain of backwards compatibility. Much like Apple when it released OS X. One thing to remember though, Windows 7 is just vapourware and a couple of videos so far.
