Microsoft announces “Office 15″ Technical Preview, Public beta coming this summer

Earlier today, Microsoft announced that the Technical Preview Program for the software suite codenamed “Office 15” has started.
The Technical Preview is a private test; those keen to try out Microsoft’s latest and greatest will have to wait for the public beta, due in summer.
Office 15 is likely to be the first version of Office to ever ship with a touch-friendly user interface, and could well sport a Metro-style UI.
As posted in the official blog post;
Office 15 is the most ambitious undertaking yet for the Office Division. With Office 15, for the first time ever, we will simultaneously update our cloud services, servers, and mobile and PC clients for Office, Office 365, Exchange, SharePoint, Lync, Project, and Visio. Quite simply, Office 15 will help people work, collaborate, and communicate smarter and faster than ever before.
