Kurt Mackie at Redmondmag.com wrote more about Microsoft Shifting To ODBC for SQL Server.  The next version of SQL Server – Denali – is expected later this year and we expect more news at the PASS Summit in October.  I will be attending PASS again this year and will post further updates.  One interesting thing to watch is how Microsoft Analysis Services will connect to relational data sources in the future.  Today, your options are OLE DB and ADO.NET.  My expectation is that the importance of ADO.NET will increase with the deprecation of OLE DB.
