The California Society of CPAs has a great introduction to the new, rewritten and clarified SAS literature in their July 2011 issue.
The article Full Tank of GAAS by Andrew M. Mintzer, CPA provides a great introduction to the overhaul of the entire body of SASs.
The article also has a great summary of the major changes in the auditor’s report.
It is quite short and well worth your read if nothing other than a general heads-up on the revised report format.
