‘HIGH School Musical 4″ is in the works – and it’s coming back to TV.

The next version of the hit TV franchise will have an all-new cast and – unlike “HSM3” which opened in movie theaters – “HSM4” will debut on the Disney Channel next year.

The new story will be about a love triangle involving kids from the crosstown-rival schools – the East High Wildcats and West High Knights – made famous in the series of movie musicals, the network says.
