My God, it's spreading like a virus, High School Musical 4 is already in pre-production and High School Musical 3 hasn't even been released yet. Nice work Disney...way to capitalize on your cash cow.
High School Musical 4 is currently set to go as a TV movie, for now...nothing is set in stone. Rich Ross, head of Disney Channel Worldwide, hopes to have the whole cast back, but knows its not likely.
I can see where the proposed reality series is tying into all of this now. New cast member? Whoever wins the reality competition. Cha-Ching.
