Tech ARP has just posted the Microsoft Office 14 Details Leaked article, you can read it over here.
"Hot on the heels of Windows 7 is none other than Microsoft Office. How can Microsoft launch Windows 7 without a new version of Microsoft Office to work with it? That would be like burgers without fries, or for the ladies, shoes without a matching handbag. Sacrilegious, isn't it?
Well, fret not. Microsoft has been working on a spanking new Microsoft Office just for you, and we have the preliminary details. You can rest assured we will keep you updated on the new Microsoft Office 14 as and when we receive more details, just as we did for Windows 7, Internet Explorer 8 and more!
Updated @ April 20 : Updated the article with the official name for Office 14, and new additions to the Office 14 program milestones."
