Scott blogged that the first Windows Server 2008 Official Curriculum course has been released and it is a good one.
Course 6423A: Implementing and Managing Windows Server 2008 Clustering
It is great to see another course dedicated to the ins and out of clustering. Windows Server 2008 has a great number of improvements that makes clustering less like rocket science and more like a core supported solution from Microsoft. If you haven't had experience with clustering I'd recommend checking out this course when it is available after May 15, 2008.
