Want to know what’s coming in Office 2010? Then visit http://www.microsoft.com/office/2010/ where you’ll find all sorts of information. There are a whole heaps of short videos on each of the Office products that’ll give you an idea of what to expect.
From the site you can also visit http://www.microsoft.com/officebusiness/office2010/ which is specifically about Office 2010 for business. There is plenty of really good information about what new features the product will have specifically for business.
Unfortunately, there isn’t a lot of information around the new version of SharePoint. There is however on the Office business site information about SharePoint Workspace 2010 (ex Groove) which allows you to take SharePoint information offline.
I would expect the content in this site to continue to grow as the product reaches a release date but for now if you want to see what’s coming in Office 2010 take a look.
