Just noticed the posting on Trika Harms her page.
During Teched the Beta exams for upgrading your MCSA / MCSE certs.
These will only be available through Teched 2007.
So if you're already up to date with all the new Windows 2008 stuff, I would say go for it.
You will be one of the first to have the Windows 2008 certification, something which might help when a customer needs to choose between two IT partners.
I will invest some extra time the following weeks to get up to date and take this exam.
