That is not what the producers are saying. They have said sequels with both casts are being considered. DOFP is not meant to be farewell to the OT cast at all. We don't know if the sequels will ever actually materialize, but we do know it's not planned as being the last we ever see of either era of characters. They obviously have ideas in mind for both.
