We have two Wii U related rumors
First there is a rumor that Wii U will come with a sort of gamer card device that is able to StreetPass just like the 3DS. It will be able to also StreetPass with 3DS. If you want more they will be sold for around 5 or 10 dollars. The gamer card would be like a low res GBA that you carry around
The other rumor comes from a tweet post that about a dev at Traveller’s Tales has been fired and might actually go to court for leaking new Wii U controller pics. The dev’s twitter account has already been closed.
Again these are just rumors and should be taken as such.
