Mention, the CSS SQL Server Engineers blog listed a note that some end of support dates were coming up.

SQL Server 2008 RTM support ends on April 13, 2010. You should make plans to upgrade to SQL Server 2008 SP1 soon.

So I think, it is definitely time to start thinking about upgrading your instances to SQL Server 2008 SP1!

Cumulative Update 6 for SQL Server 2008 SP1 (KB #977443)
The SQL Server 2008 builds that were released after SQL Server 2008 Service Pack 1 was released

Cumulative Update 9 for SQL Server 2008 RTM (KB #977444)
The SQL Server 2008 builds that were released after SQL Server 2008 was released

AND I think It's time to vote at MS-Connect for Service Pack 2 for SQL Server 2008!
