After the CCNA: R&S exam in a month I plan on picking up the MCSA track.
Which one is going to be better for me in the long run? - I plan on doing the MCSA 2008 then upgrading to MCSA 2012 then moving into MCSE: SI 2012. MY thought's 2008 exams build off previous exams and it will be a learning curve knowing the older commands lines but when I master them moving into MCSE: SI 2012 they should be easier?

Is this crazy talk or would 2012 be the better approach; bear in mind my current employers and my home-lab is licensed 2008 R2 with Technet keys before Technet went poof.
I attempted 70-640 4 years ago before I even got my A+ and failed it with a 340 (I know horrible - but I wasn't ready at all knowledge wise), and I do think now after 4 years my skillset are much better considering I've been a 3 forest with 2 domains per forest system administrator for the past 7 months and prior to that I was a 2008 R2 system administrator for 3 years. I recently just upgraded the employers network from 2000 Native to 2008 R2 and all of the servers to the 2008 R2 level.
Thoughts?
