Wikipedia:Articles for deletion/Doctor Who 2008 Christmas special
says that it's okay to have future events providing there is significant coverage by secondary sources.  Elections are a good example.  A trailer is not a sufficiently reliable/verifiable/source, and in the absence of further coverage, I suggest this is recreated nearer the time.  Fails  for that reason
