Are you sure Haruhi announced it as "14" ? because.., well.. I guess we all thought that with the 00 there would only be 13 episodes.
Making it 00 (1)+13 = 14 (entire series)
By the looks of it there will be a ghost number somewhere in the count.., number this that will probably be when the 00 was made ^^
Or so I at the moment think.., its Haruhi.. anything can happen
