It looks like the next planned announcement won't come until January 2nd.
EDIT: 1 more TBD box got added on the lineup page (http://www.crunchyroll.com/lineup
). So after today's announcements, there are 7 more TBD boxes.
EDIT 2: 2 more TBD boxes got added for Catalog Titles as well (2 of them for 12/28).
