One of the main reasons I picked up a Switch is for this.
It will 42 racers and 48 different tracks, which is phenomenal imo.
They are bringing back old items such as the ghost that would make you invisible and also allowing racers to hold 2 slots for boxes.
Like mentioned previously, its Battle mode which is getting the most overhaul. It will entail the following:
Renegade Roundup: Making its debut in Mario Kart 8 Deluxe, this new mode has one team trying to capture the other and put them into jail before time runs out. The opposing team must try to escape and can break their own teammates out of prison by pressing a button under the jail cell.
Balloon Battle: In this oldie but goodie, players earn points by popping balloons on the back of their opponents’ karts.
Bob-omb Blast: Originally seen in the Mario Kart: Double Dash game, this mode finds players throwing a barrage of Bob-ombs at opponents.
Coin Runners: By racing across the Battle course, players try to collect the most coins as possible in this fast and frenetic mode introduced in Mario Kart Wii.
Shine Thief: Steal the coveted Shine Sprite and try to hold onto it for a 20 count in this classic multiplayer Battle mode.
