Windows Server 2008, Visual Studio 2008 ("Orcas") and Microsoft SQL Server 2008 will all launch on February 27, 2008! So said Microsoft Chief Operating Officer Kevin Turner at the Microsoft Worldwide Partner Conference 2007 in Denver Colorado. The press release is here. Scott Guthrie later clarified in a comment on Scott Dorman's blog that release is often several weeks or months before the official launch.

So it looks like we'll be able to start working with the new products around late January - which is good timing because I'm sure by then we'll be completely adapted to the huge changes in SQL 2005, Office 2007, .NET 3.5, WF, WCF, WPF, WWII, etc and ready to grab the next wave!
