Microsoft has been really busy finishing up all their 2010 products! After the Visual Studio 2010 RTM a couple of weeks ago they now have announced that all of the Office 2010 Suite (including SharePoint Server 2010) and SQL Server 2008 R2 have RTM'ed.
I have not been able to find out when the Office 2010 Suite will be available for download on MSDN, but SQL Server 2008 R2 will be available on 5/3. For details on the SSRS changes see Robert Bruckner's blog post.
Sorry for the lack of updates, but things have been pretty quiet as SQL Server 2008 R2 and Visual Studio 2010 are getting ready for RTM.
Go to this link for some free training from SQL PASS! Most of it is focused on SQL Server 2008 R2, which will be very timely in May with RTM coming around or just before that timeframe.
