I can't wait for it, though it's not gonna air for a while.
I think Carly, Sam, and Freddie should go to Hollywood Arts. As for the whole Shelby and Harper thing, it'd be cool if Tori had a history as a fighter under the name of 'Shelby' and Andre used togo under 'Harper'. Trina won't matter because her part was minor. Anyway, Then the iCarly gang could point it out about Andre and Tori and that could be part of the plot. And I could see Jade and Sam getting along, as well as Robbie and Freddie.
