Windows 2008 certification exams are starting to go to beta

As noted here, the Windows 2008 certification tests are starting to trickle out. These are the non-upgrade type of exams, i.e. not an upgrade exam from MCSE 2003 to MCSE 2008. To a certain extent, MCSE 2008 doesn't really exist.

Tests available now:
70-640: TS: Windows Server 2008 Active Directory, Configuring
70-642: TS: Windows Server 2008 Network Infrastructure, Configuring
70-643: TS: Windows Server 2008 Applications Infrastructure, Configuring

Beta exam period runs: November 27, 2007– December 21, 2007
