A question for High School Musical fans only ?

They have annouced a 4th High School Musical movie, but the 6 main stars of the first 3 movies will not return, so it is now up to the youngsters that they will get, to contuine the series into a 4th movie. So without the main cast members, of the first 3 movies in the 4th movie, do you plan to watch it when it gets released? Also please tell me why or why not?
