Some say its real. And when I looked on Google news, I saw rumours that it's going to release early 2017.
I want the pack to be Splatoon x Mario Kart 8. The characters, karts, cups and their courses will include: (And I'll ask why I want them, this is NOT the leaked list, if you were wondering)
Characters:
Inkling Boy and Girl
Diddy Kong
Bowser Jr.
Karts:
Splatoon Buggy (ATV, Inkling Boy's signature ATV)
Excitebike Bike (Well, we got the course, why not the bike? It can be in different colors by different racers)
Banana Wheel (In Drift Bike, Diddy Kong's signature bike)
Soda Jet (C'mon, it was my favorite kart back in MK7. Can it come back plz?)
Courses:
Squid/Inkling Cup:
Kalimari Desert (We saw it in the Twitter post, so it'll work. And an orange shy guy can appear as a staff ghost here, as there was a shy guy as a staff ghost in MK7)
Waluigi Pinball (Just, plz Nintendo. Its not fair you brought it back in MK7.)
Bowser Jr's. Circus (Its a reference to Super Mario 3D world, all the 3D world bosses and characters will be there)
Inkopolis Circuit (For obvious reasons. And Inkling Boy will be the staff ghost here)
Gem Cup:
Maple Treeway (In the 2nd DLC pack, in the Fall version of the Animal Crossing course. There are piles of leaves that act the same way as they do in Maple Treeway. Perhaps Nintendo is hinting this course back in DLC 3)
Yoshi Desert (I know, another desert track in MK8. But we need another colored Yoshi as a staff ghost in a DLC pack. The first was Red, the second was Orange. This one will be yellow)
Treacherous Temple (This course is the reference to the Gem cup, as its the Super Gem from Captain Toad: Treasure Tracker. In DLC 1. It was the Egg cup, and we got Yoshi Circuit. In DLC 2. It was the Bell cup, and we got Super Bell Subway. In DLC 3, it could be this. And as the course name suggests, its a very dangerous course, with lots of twists, turns and obstacles. I, myself might be good at it if it were to be real. And captain Toad and his assistants will be spectating in the course too. And, because Captain Toad will not be a DLC character, Toadette will be the staff ghost here)
Port Town (Another F-Zero track. We got Mute City and Big Blue, we'll get Port Town. Inkling Girl will be the Staff ghost here)
Phew, I said too much already. I'll stop, lol. But tell me what you thought of my DLC 3 prediction.
