What will be the new gimmick of MK9?

[Mar1217]

Plz no Nintendo Kart wishful bullshit. This is not a smart gimmick.
There's no problem a few select of those to supplement your roster but it cannot become THE feature everyone should look for.

Thankfully, it seems there using known quantities of characters from the series so far so I doubt the Nintendo Kart thing is even a thing, except for possible exceptions(Like the F-Zero tacks were)
