Edit:

This GIF isn't mine. I just think it's hilarious. :)

This is awesome news!
The only thing that disappoints me is the Tanooki Mario and Cat Peach. They should have replaced them with Diddy Kong and Birdo.
New courses, new vehicles, + Link, Villager, that strange Animal Crossing character that I always forget the name of and Dry Bowser are fantastic additions!

Oh and a freaking F-Zero track! That is amazing.
I hope it is a hint at things to come. F-Zero 2015?

Edit: I remember! It is Isabelle. 

Forgive my insolence of skipping reading all of the posts, but I saw this news and squeeled...

A real crossover for the first time with Link and an F-Zero "kart". I couldn't be happier. Add to that more tracks from the same people who already created some the most ingenious and easily my most loved tracks of all time?

DLC Purchased. And it ain't even out yet.

It seems more like someone jumped the gun to me. I can't see any reason as to why they would only put this up on the UK store.

I'm still laugting 

Someone's been lurkin NeoGAF. ;p

:O

nice gifs. wait a sec... Is that F-Zero in the last screen?

yes. There will be a F-Zero track and some cars from with the frist DLC pack

noice!
