Towards the end of 2010, Microsoft made some changes to the Microsoft Certified Master for SQL Server 2008 program.

The process to certification required to have a 3 week bootcamp/course in Redmond. This has changed now.  It has been mapped to 2 exams.

Get information from Microsoft Learning with regards to the changes, process, resources and pricing for the certification exams.  http://www.microsoft.com/learning/en/us/certification/master-sql-path.aspx

What has happened here too, is some SQL MCM rotation Instructors and SQL MCMs  have created materials to prep for those exams.  I see this as a huge benefit for individuals who are planning to take on the MCM, but really it is of huge benefit for all individuals who deal with working around SQL Server on a regular basis.
