Baby Rosalina, Pink Gold Peach, and Mii are joining the ever expanding roster of Mario Kart 8! The two brand new characters are making their debut into the Mario universe, while Mii is returning from both Mario Kart Wii and Mario Kart 7.
Of course, this does not mean that this is the final roster. Nothing has been said about hidden and unlockable characters, or even future DLC. Keep your fingers crossed!
