After tons of feedback from the community, MS has decided to release another Service Pack for SQL Server 2005. More information on the Data Platform Insider Blog. Of course, there's not much detail about what will be IN the SP, but I think this is a huge step in maintaining good standing with customers. While many people jumped at the chance to go from SQL Server 2000 to 2005, the jump to 2008 will be a little more hesitant, mostly because of the difficulty in moving database platforms in production environments. Hopefully, this SP will give people a "longer life" in SQL 2005, while giving them the opportunity to more carefully evaluate SQL Server 2008.
