The Microsoft Certification team continually monitors industry trends and then revises exams and certification requirements to keep pace with changes in technology. On a regular basis, new exams are introduced and older exams are revised or retired. Certifications you have earned remain valid even if qualifying exams have been retired. When an exam you passed is retired, your transcript retains the record of the exam and identifies the exam as retired.
Most exams for SQL Server 2008, Visual Studio 2008, Visual Studio 2010, Windows Server 2003, and Windows Server 2008 will be retiring on July 31, 2013. Exams for SharePoint Server 2007 and Project Server 2007 will be retiring on January 31, 2013. New exams for SQL Server 2012, Windows Server 2012, and Visual Studio 2012 are already available.
Planned retirement dates for additional exams have been announced, including exams covering Windows XP and Lync Server 2010, as well as the SharePoint Server 2010 Masters exams. Note that both exams and dates planned for retirement may be subject to change.
The liked list of retirements includes only already retired exams, not retirements in future. The link name is missleading. I need to plan a training project and thus the exact future dates of retirement.
