I just ran across this article the other day thanks to a Twitter post by ferringer 🙂  http://www.macworld.com/article/137950/2009/01/officeupdates.html.  In summary of the article, Microsoft’s Business Until for Mac is going to be issuing some updates of Office 2008 and Entourage as well as releasing Document Collaboration Companion for the Mac.  This will allow user to better integrate there Mac with SharePoint and Office Live Workspaces as Microsoft moves more and more into Cloud Computing and Software as a Service.
