One of the advantages of MVA is that one can follow online training based on his/her own pace. So whenever you have an hour or so to spare, you can surf to MVA and extend your knowledge on Microsoft technologies. And for me being Dutch there is another HUGE advantage: it’s FREE!
And on top of it, I expect to see stuff about Windows Server 2012 in it as well. Don’t know the time frame but my personal guess (based on nothing but just a feeling) is that it will be rather sooner then later.
So whenever you work with any System Center 2012 component, go to MVA Private Cloud track and LEARN!
