I hope that's not final because it's missing a lot of franchises.
Also, "for the first time ever"? Please! Nicktoons Racing released in 2000, and it featured CatDog and Angry Beavers! C'mon, son! At least get Fairly Odd Parents and Danny Phantom.
From the wiki:
"Twelve Nickelodeon series have been confirmed for the game, but so far only four have been confirmed through game screenshots: SpongeBob SquarePants, Teenage Mutant Ninja Turtles, Hey Arnold!, and Rugrats."
