Have you heard if training kits for 70-466 and 467 on the roadmap?
I was looking for the same thing. I found the training kits for the MCSA exams very helpful.
there seem to be training kits for SQL Server 2008 but I haven't seen anything for 2012
Here's a link to the book I used. Go to oreilly.com and search for sql 2012 training kit. search.oreilly.com
