Games are software. Changing the upper management/ownership isn't going to change deliverables. If anything, it could delay releases even further out with new overlords. Certainly they can clean house of the former companies HR department as well as any senior leaders that did nothing with previous issues.

It will take a long time before anything material comes from this from a games perspective. I would assume legal agreements are in place for cash-cow games like Call Of Duty on other platforms so that should alleviate any anti-competitive investigation.
