The guys @ Microsoft have been busy improving the quality of SQL Server even more.

Although I see the benefits in the Incremental Servicing Model many people like the "certainty" of a good old service pack. Because Microsoft listens to its customers they have decided to release Service Pack 3 this year. More information can be found here.
