I don't really think that leak is real for several reasons. Mostly because it contradicts the Shovel Knight rumor.
Also, I just want to say that I'm not biased or anything. I could care less if he gets into Smash or not. I've never played Shovel Knight anyways
.
Anyways, don't forget the two key things with this leak.
1.) Tama had multiple sources.
2.) Amazon selling Nintendo eShop games came true.
I do still strongly believe in this leak, although anything can change at any point. Maybe this is all misinformation like
@Parallel_Falchion says it could be? Until then, we won't really know until we get any type of official confirmation from Nintendo.
