I hope you weren't hoping to hear Hatsune Miku talk to SpongeBob in Sonic Racing: CrossWorlds, as none of the crossover characters will be voiced: "This is just unacceptable for a $70 game"

Jet The Hawk, Shadow The Hedgehog, Sonic The Hedgehog, Knuckles The Echidna, Eggman, and Tails The Fox race towards us on a variety of vehicles in Sonic Racing CrossWorlds, emerging from ring portals depicting various levels from Sonic history.

Despite being a $70 with paid DLC, none of the collaboration characters in Sonic Racing: Crossworlds will be voiced in the game.

Sonic Racing: CrossWorlds is picking up the slack from Mario Kart World, as Sega is bringing in characters from outside of the Sonic universe into the fold. But while having the likes of Yakuza's Ichiban Kasuga and Persona's Joker are within the same realm of Nintendo adding their own characters to Mario Kart, Sega is going one step further with crossovers every month with characters outside of its wheelhouse like SpongeBob SquarePants, Minecraft Steve, and Hatsune Miku (who is kind of a Sega character, but owned by Crypton Future Media) showing up in game.
