CUNY probably has an internal waitlist that is not released to the applicants (this is what I guessed because I never see anyone posting "CUNY waitlisted" on the self-report page on GradCafe, since I almost check it everyday since late Feb. But it could also be that waitlisted people just didn't post them here). The professors sent several emails to accepted students that if you decided not to attend, please let them know sooner than later, so that students on waitlist can be accepted, too. So at this time, it is really up to the other accepted students' decisions. I declined yesterday and saw an acceptance post on the self-reporting page on the same day, so the school admission itself is very efficient (which means they are not a department that forgets anyone). Hope this helps you.
