Worth the wait?

[zmpmag...@yahoo.com]

This question is for those who are MS SQL Server MCTS or MCTIP certified.

I'm currently doing exam prep for a couple of MCTS certs in SQL Server 2008.
Given MS's new "expiration policy" for MCTS/MCTIP (ie. certs expire with the
"next major release" of the product), and with the pending release of SQL
Server 2012 (Denali) this year, I can choose either to take the 2008 exams
now and a 2012 "upgrade" exam later, or just wait for the 2012 exams. What I
don't know is, how much time does it take after the product is released for
the certification infrastructure (i.e. exams, training materials, etc.) to be
ready. If not long after release, then it makes sense to wait. If takes more
than 1/2 a year or so, it may make sense to take the 2008 exams now and
then take the "upgrade" exam.

What has been your experience in re: the "time interval" between release of
the product, and availablity of the exams, training materials, etc.?

Many Thanks.
