Last week, there was an update to the list of certifications and the numbers of people certified.The location of that page is at http://www.microsoft.com/learning/mcp/certified.mspx
Also on the certification front, the MCITP exams have been released for Microsoft Server 2008. Trika covers that off here (http://blogs.msdn.com/trika/archive/2008/04/09/earn-your-mcitp-on-windows-server-2008.aspx) with some answers to some common questions. My plan is to write the 70-646 exam in the near future then down the road, probably after I finish up the MCSE on 2003, is to write 70-643 and 70-647. Note there was the first to know promotion going on which got 40% of one of the MCTS exams, and one of the MCITP exams. If you were signed up for this, you should have received your code.
