When I originally got the acceptance pending open seat call 2 days ago, I was a little to ecstatic to ask any follow up questions. So I called today and spoke with Dolores of SOMA admissions, she is super nice!
Per Dolores, the admissions committee is still deliberating whether the "accepted pending open seat" list becomes a "deferred acceptances to Class of 2021" list, and that nothing is for certain. However, this has happened in the past so lets stay positive. As of right now the only available CHC placements are in Ohio and one of the Carolinas (I think it was South, not 100% on my memory right now haha) and that there has been multiple previous years in which admissions have pulled students off of the alternate list.
When someone is accepted, he/she then has 2 weeks from the acceptance date to pay the acceptance fee of $1000. If they do not do so, their acceptance is then given to someone else, which will be to the next person that is ranked on the "acceptance pending open seat" list. If a prospective student pays the $1000 acceptance fee within 2 weeks, then they will have that seat, and CHC placement until June 15th, where the student will have to pay the pre-registration fee. If someone does not pay the pre-registration fee on June 15th, then that seat is forfeited, and more people will be moving from the"acceptance pending open seat" list and even the alternate list if the "acceptance pending open seat list" is exhausted. Anytime between now and June 15th we can get a call for getting a spot in Class of 2020, depending on currently accepted students paying their fee in 2 weeks.
What I took from this, is to expect a lot of movement around June 15th. Dolores even stated that she is always moving students around from CHC to CHC and even off the ranked lists, so anything is possible! Best of luck everyone, there is still time left
