I guess that's the plan, but given the state of openGL on the Mac, I'm not too optimistic about BF4 looking as good and running as well on OS X. Plus, the job position at DICE is apparently still open, so work on the OS X port may not even have started. OS X openGL engineers are pretty rare I suppose, and not all may want to move to Sweden. You would have to find the right one looking for a job.
