Server 2012 R2 Update

I'm looking to start the Server 2012 MCSA in the next week or 2, and have started looking at resources /books to purchase, . Going by 03 & 08 updates can anyone give me an of how much the content/objectives will change, how soon the updated books are released after the objectives are? Since the R2 update is released on January, does the exam in become the R2 version in January also, or does MS give you a while to do the original test if thats what you have been studying, or can you choose to do the old exam for a period?

The R2 changes are seemless, you take the same exam number but the questions change to reflect the new R2 objectives.
Good luck with your tests!

Any insight and opinion is appreciated.
That is basically what I am doing....except I am using Microsoft Second Shot to hedge the bet. I am not sure I am completely ready for this exam but knowing that if I fail it I can retake it in a couple of months for free makes it a lot easier.

Unbelievable, they have put the R2 books released date back AGAIN. They are only 12 months late! lol
I was going to do 410 before the R2 changes but I've changed my mind, I'm going to wait instead and do some more VMware tinkering...
