Microsoft has released the upcoming version of SQL Server, SQL Server 2011
code-name SQL Server Denali CTP1
(Community Technology Preview 1) for SQL Server database professional, SQL Server database administrators and developers.
The MS SQL Server 2011 release date
of first CTP, CTP1 is 8th of November, 2010.
We can expect the next CTP within 3 months time. And a similar timing schedule is leading me to expect the MS SQL Server 2011 release date of RTM version
at the end of 2011.

After you download Microsoft SQL Server 2011 CTP1 from Microsoft Downloads and install SQL Server 2011, to see what is new in SQL Server 2011 and work with samples, you can also download SQL Server 2011 sample databases and AdventureWorks sample database for SQL2011
