Tanti auguri a te... tanti auguri a te... tanti auguri Visual Studio... tanti auguri a te!!! 
No, that's not the name of a new feature coming in Visual Studio code name "Orcas" or Visual Studio Team System code name "Rosario". March 2007 is the Visual Studio Decennial since it marks the 10th anniversary of the release of Visual Studio 97, the first release of Visual Studio. Microsoft PressPass has a page o'quotes from numerous Microsoft customers and partners (Comments on the 10-year Anniversary of Microsoft Visual Studio, March 2007), and Prashant Sridharan is celebrating the anniversary in his keynote this morning at VSLive! in San Francisco, where Sam Gazitt is making his on-stage debut.
Update: I'm happy to find a blog post by someone who attended the keynote. See Day 2, Keynote.
