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.

Half-pipe 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.

Grand Prix
A mode where you compete a cup for a ranking. You can either get 0 star rank, 1 star rank, 2 star rank, or a 3 star rank. You can unlock a character and veichles by going through each cup. You have 50cc, 100cc, 150cc, mirror mode (150cc), and 200cc. Mirror mode is unlocked by completing the special cup in 150cc and 200cc is unlocked by completing the special cup on mirror mode.

Time Trials
A mode where you can beat staff ghosts for a fast record. It can be played on any cc. You can race up to 100 ghosts at a time.

VS
A mode where you can race with custom rules. There's been a new change where you can pick which items you want to have on and off.

Battle
A mode where you can battle on stages playing multiple modes. You can have custom rules like in VS. You can also pick which items you want on and off. Items like lightning bolts, blue shells, bullet bills, mega mushrooms, and more will be used in battle.

Battle Modes
Balloon Battle- the classic battle mode where you try to pop your opponents balloons. You start with 5 balloons. When you're out, you respawn with 3 balloons.

Renegade Roundup- a retro mode where there's only teams. One team plays as the cops (they have piranha plants to eat the renegades) and the other steam plays as the renegades where they have to avoid the cops and open the cells.

Shine Thief- a retro mode where you have to steal the shine from the player who has it.

Shine Drivers- a returning mode from Mario Kart DS. Some fans perfer the mode over coin runners because of "elimination process". It's name will be changed to "shine drivers" because we're driving not running.

Bomb-omb Blast- a retro mode simlar to balloon battle except you only use bomb-ombs.

Raining Banannas- a new mode where you only use Banannas and have balloons from balloon battle and bomb-omb blast. When you throw a bananna, it goes into the sky and it stays there. You have to avoid other banannas. It's hard to tell which is which. If you slip on your bananna or your teams bananna (if you're playing with teams) you don't lose a balloon.

Mission Mode
A mode from Mario Kart DS. You do missions like boss battles, boss races, ect.

Double-Dash Mode
A mode where you race in the same karts. You can press "SR" on the joy-con or pro-controller to switch the racer (and item). There will be special karts for double-dash.
