wrote an email to the suppport recently they sent this in response.
I mentioned how C&Y were a positive apartment to watch everyday and that them leaving may cause myself and others to leave and so forth.
Thank you for your letter, we will notify our appropriate department. Also, Carla and Yanai might return to the project soon.
take it as you will, but the way they say 'Also' seems to me that they will return at some stage possibly at a different apartment something bigger for themselves with better cameras and can entertain more guests.
Neither C or Y seemed to be upset they were leaving at the last point they walked out the door I do just hope they make a comeback
