As an update to my previous post, SQL Server 2005 SP2 is now officially available. The SP2 build is 9.00.3042. A SP2 landing page is available too that includes links to the SP2 release, KB articles, marketing information about the benefits of SP2.
As a personal contributor to Service Pack 2 (mainly in the areas of Reporting Services SharePoint integration and Analysis Services), I hope you enjoy it!
