A Disney spokesperson confirms to TV Guide that plans have changed for the next film in the "High School Musical" saga.

The first two direct-to-cable TV movies have proven such huge success stories that a third film was already planned, a feature set during Halloween entitled "Haunted High School Musical".

Now it seems, the third entry will be centered on the fast-growing "kids'" senior year with Troy, Gabs, Sharpay and the gang all back - despite the fact none of the major stars have yet inked deals.

Disney has also just announced that they'll release the second film on DVD this December 11th. The the extended edition, running 111 minutes, includes a never-before-seen music sequence, rehearsal footage and music videos.
