Well this isn't going to happen any time soon, if we take a look at the second image, it is created by a TGiuseppe94, who from what i understand, is more interested in My Little Pony, than having anything to do with hacking the Wii U:

Now whilst today isn't over, i want to apologize for this mess, i wasn't the one who posted the info on WiiUHaX, but i am the sites owner, so i am partly to blame for this crap, i will monitor more closely what gets front paged.
The person who did post it on the front page is an admin on the site, he and harryoke from PS3HaX where in contact with these so called hackers, i have not spoken to them and i do not know who they are, so i'm guessing that TGiuseppe94 is one of them, because of the signature on the image.
Edit:
Though it could be that TGiuseppe94's image was used, here is the original one:

He might not be involved.
