I wrote an article for Simple-Talk that was published last Monday:

A first look at SQL Server 2012 Availability Group Wait Statistics

AlwaysOn Availability Groups have their own host of associated wait types, so I thought I would investigate the various wait stats that accumulate based on different scenarios.  I see this topic evolving over time, but I thought I would kick the subject off.

If you encounter other interesting patterns, feel free to share in the comments of this post (or the article itself).
