Microsoft is distributing the Office 2010 bits via its Connect testing site. The bits hold the build number 14.0.4006.1110 meaning they are older than the recent "beta" leak. Office 2010 promises tighter integration with Windows 7, full Ribbon UI for Outlook and compatibility with Microsoft's forthcoming Office Web Applications. Office Web Applications are not available for testing yet, Microsoft employees are currently "dogfooding" the bits internally and a wider beta should begin at the same time as Office 2010 beta is offered publicly.
