High School Musical 4: East Meets West
On April 8, 2008, Disney Channel Worldwide President Rich Ross stated that script was being written for the fourth installment of High School Musical. However since Zac Efron and Vanessa Hudgens' characters have graduated and headed to college, they will not be reappearing, Hudgens has confirmed this via Twitter. The filming will be done by choreographer and director Jeffrey Hornaday and will debut on Disney Channel in 2010. Casting is underway for the fourth installment, which is set against the cross-town school rivalry between the East High Wildcats and West High Knights.

To me, I believe they should not keep carrying this on and on and espically with the main loved characters left because they have graduated.
Well, Let's see what goes on and [spoiler:3ek28utg]not[/spoiler:3ek28utg] hope that it goes well.
