Mario Kart 9 or Switch

Mario Kart 9/NX is the 9th installment of the Mario Kart series. It will be released on September 1, 2017 for the NX. It will be called Mario Kart 9 or NX based on what Nintendo picks (although they will probably call it Mario Kart 9). It will be kinda like how most people predict it.

Gliding
Nothing has changed except that gliding and cannons will be 2 separate things so you can dodge lightning, blue shells, and other items in cannons, but you will still have the glider on in the cannons.

Underwater Driving
Nothing has changed.

Anti-Gravity
Nothing has changed.

Double Item Box
You can now pick with item you want to use by pressing "SL" on the joy-con or pro controller.

Double-Dash Karts
They will return, but only usable in "Double-Dash" mode.

Halfpipe Tricks
They will return from Mario Kart Wii. Nothing has changed.

Kart Combo
You can pick which drill you want your kart to use. You could use karts, bikes, ATVs, and now trucks.

Driller
It was originally planned for Mario Kart 8, but was scrapped. You can drill to another side of the course. We don't know what it will look like, but we will have to wait to see.

Underlava Driving
You can drive under the lava of courses. Simlar to underwater driving.

Coin Collecting
It is where you can collect coins to increase your speed a little bit. It will be retired because most fans hate it and they say "it doesn't do anything". It can unlock veichles, but you will now have to unlock them by a cup like in Mario Kart Double Dash and Wii.
