If Blizzard doesn't really goes off their routine, I would assume Dark Rangers and Tinkers will become the next hero class, I just personally assume DR will be first. But then again, I don't want to argue with you, you seem to be a very new player who has very little experience with how Blizz introduced classes in the past while ignoring actual arguments and explanations how it worked by the past by more experienced players, instead becoming very emotional. So believe what you believe.
