To Be Announced

1) Commonly abbreviated "TBA" on tickets and the like, To Be Announced is a common occurrence in sports and concerts. It simply means that a contender or act has not yet been officially announced to appear at the venue by the powers-that-be. Although similar, with a bit of overlap, this is not to be confused with "To Be Determined" (TBD). That one implies that such an announcement cannot be made at all until certain conditions are met.
