Quick input from a guy that does not own a Wii U, but is very familiar with how brazilians behave on the internet (because I am one)
Brazilians are renowned shitposters, trolls and love to take advantage of any hype-inducing subject or topic.
Brazilians are also not really known for having logic analyzers, debugging tools and whatnot because of their prohibitive cost down here.
With lots of people working on this, what are the chances that the fabled piracy solution for the Wii U comes from Brazil?
My advice? Take this with a grain, or rather, a shitload of salt.
P.S.: I would love to be proven wrong though.
