Ashley Tisdale is the first High School Musical star to comment on the recently announced High School Musical 4. "We love HSM, but we kind of have to move on. It will always be a part of us that we loved to do."
Zac Efron hinted several times that High School Musical 3: Senior Year was his last HSM project, especially when he told MTV "This is the legacy that we leave. I think it's going to be a good way to go out with a bang."
Vanessa Hudgens told "Extra", "It’s the final one which is so sad because usually we always get to say, ‘We’ll see you on the next one’ but this time, there isn’t going to be a next one!"
It's interesting... either Zac and Vanessa were kept in the dark about High School Musical 4 or they REALLY wanted to get the point across that Senior Year is the last movie for them.
