I have started to go through the blue print, and today I downloaded the Exchange kit. The link in doc downloads the documents at it relates to vSphere 4. A lot has changed as far as what supported, what not, ectt... So I am guessing either the new DCD does not cover things that have changed, or the blueprint should be updated to point to the vSphere 5 stuff.
Thoughts?
Have you looked at the resources here?

The blueprint has already several useful pointer to other docs.
But look also at: http://vinfrastructure.it/2012/05/vcap5-dcd-study-guides/
