Office 2010 and the new name for Groove
As of yesterday @ TechEd US the Office team launched a dedicaded blog site for Office 2010 related stuff.
One of the first posts annouces the long forseen change in Groove, which will be known in the future as SharePoint Workspace. As stated in MSFT presentations before: "Groove is to SharePoint what Outlook is to Exchange". Seems like there catching up on that promise :)
