Rumor: Nintendo's leaked prototype art.

[MaxwellGT2000]

Liked the train boat as well, but prototype art? first time I've ever heard concept art called prototype art lol

And all these pictures are taken out of a book it seems so not so much of a leak, since Nintendo wouldn't make a book of something they wouldn't want getting out, plus leak means its something people don't know about, all this stuff is of already released products just development concepts
