MCSA 2012 vs. 2008 R2

I'm enrolled at WGU and unfortunately I have failed the 70-640 3 times at this point, and as a result, I am switching my program to general IT to graduate sooner and save money. I'm fairly close to passing (I think) as I'm scoring in the 620-640's. While I think I could pass the 640 given some more time to focus on my weak areas which seem to primarily be DNS and Roles and Services, I don't want to waste any more money trying to push through the 2008 certs when 2012 R2 is out already. I know, I know, most employers are still utilizing 2008 including where I work, however we are starting to upgrade servers to 2012 and I think I'd rather just switch focus and start that path to give myself some more breathing room before the next iteration comes out.
That said, it seems folks are having an easier time with the 2012 exams, though it may just be that those who are posting results are just better at exam-taking. I've heard CBT Nuggets and the material on these forums is enough to pass; contrast with what seems like no matter what I do in studying for the 640... labs, ms press, CBT nuggets, technet (though admittedly less so), and enough practice tests to send me into a coma, I still can't edge a better score. I have little real world experience with 2008 except for some basic AD tasks in my current job as desktop support, but my employer has stated there may be a need for another network person, but as of now we only need two at our site and they aren't going anywhere for a while. I'm trying to show that I know the software so that I might at least be able to get some experience working on it since I have doubts about another position opening any time soon, and these guys will be here for at least another 10-15 years. In other words... I would like to have some credentials + experience working with the software that will be out for some time so I can be more marketable elsewhere.
Thoughts?

If I were starting all over though, I would definitely go 2012 first. I have really struggled with the 640 and I believe I would've already passed the 70-410 by now. We have 2012 servers at work here and, for the most part, once you get past the UI differences it is very similar. Looking forward to seeing what 2012 R2 brings.
unfbilly11, it sounds like we're in a similar boat. The 70-640 as you say just seems to cover way too much material, but i agree, I have learned quite a lot. It's why I'm trying not to be too hard on myself for not passing, but it's still frustrating.
