"Microsoft on Thursday detailed some of the new features in its forthcoming Office for Mac 2011 suite, including co-authoring tools, Web apps, and a redesigned ribbon interface more consistent with its Windows counterpart."

According to Eric Wilfrid, MacBU General Manager at Microsoft, "Together with your team -- officemates, family or classmates -- you are part of the community that helps shape each version of Office for Mac. You’ve told us that working together across platforms is a priority to you and that’s why we are making Office for Mac 2011 the best, most compatible productivity suite on the Mac." No pricing set yet, but some of the specifics are co-authoring tools that allow multiple users to work on files from different locations with real-time updates, access to Microsoft Web Apps from within the program so you can share documents from any machine with an Internet connection and allowing Outlook to import .PST files from Outlook for Windows.
