Windows Panorama?

Microsoft to Introduce Panorama; Live Arcade for Vista? on Shacknews plays up some rumors they've gotten wind of via some of those "reputable sources" of a project called Windows Panaorama, which they liken to an Xbox Live Arcade-type service for Windows Vista. They have gotten corroboration of the project's existence from Microsoft, but no verification of what it actually does, and they speculate that the facts may be unveiled at the Microsoft Gamefest conference in Seattle next week.
