Microsoft announced at official Office 2010 Engineering blog that Office 2010 has reached the released-to-manufacturing (RTM) stage.
Here is what "Takeshi Numoto" (Corporate Vice President, Microsoft Office) announced at the blog:
Earlier today we reached the release-to-manufacturing (RTM) milestone for Office 2010, SharePoint 2010, Visio 2010 and Project 2010.
Our Volume License customers with active Software Assurance (SA) on these products will be one of the first to receive the 2010 set of products. They will be able to download the products in English via the Volume Licensing Service Center starting April 27. Customers without SA will be able to purchase the new products through Volume Licensing from Microsoft partners starting May 1.
We will officially launch Office 2010 to our business customers on May 12.
Office 2010 will first become available in retail stores in June in the US, and customers can pre-order these retail versions of Office 2010 at store.microsoft.com/OfficePreorder today to receive Office when it becomes available.

MSDN and TechNet subscribers will be able to download Office 2010 on April 22.
The build number of RTM is 14.0.4763.1000.
