Hi,
The current (new) MCSD tracks available do not have MCSA exams listed as a prerequisite:

The Q&A on the link above also answers the question that the current/new MSCA tracks are not required:
Q.Why is there no MCSA certification for developers?A.
The Microsoft Certified Solutions Associate (MCSA) certification identifies a set of core technology skills that are applicable to multiple technology solutions. For MCSD, there weren’t enough common skills to warrant a fully separate MCSA certification.
