We're trying to upgrade from SQL 2005 to SQL 2012 and figure that just bypassing SQL 2008/R2 makes sense because of that. We'll be able to take advantage of a lot of features that are new to us, but not sure how many 2012-only features we'll use right away. I'm sure we'll work in some windowing functions and at least consider Always-On a little more, but the biggest thing I see us using sooner is filtered indexes.
