Matt Prokop (who played the Troy Bolton wannabee in HSM3 posted on his Myspace page that he will not be in HSM4!

Not only will HSM4 not feature your loved wildcats: Troy, Gabriella, Sharpay, Ryan, Chad, and Taylor, but I will also not be apart of it. Disney decided to go with a completely different story line. I'm so thankful to be apart of HSM3 before they decided to change everything. Enjoy the new characters....... whoever they will be.
