From the certification page:
http://www.microsoft.com/learning/en-us/mcsa-windows-7-certification.aspx
you need exam 70-680 plus either 685 or 686 (not both).
Apparently, the only change after January 2014 is that these exams will no longer give you the MCTS and MCITP certifications, but the requirements for the MCSA will be unchanged (in other words, the sentence that says "Exams 680, 685,
and 686 will still be required for the MCSA: Windows 7 certification" seems to be in error, or at least in contradiction with the main content of the page -- the "and" should be an "or").
