It has been reported by ABC News that $2 million worth of Wii U consoles have been stolen from a Nintendo warehouse, located in SeaTac Seattle Air Cargo.
This means that 7 thousand Wii U consoles were taken by the thieves, whom apparently drove two large diesel trucks into Nintendo's distribution site, which is inside the warehouse, to then proceed to take all the merchandise.
At this point, there is no information about them, yet the local police is doing everything they can in order to catch the robbers before they try to sell all these consoles.
It is possible that there is a mixture of different consoles and accessories, but this hasn't been officially confirmed by the authorities, yet it is something to keep in mind, as ABC News has called the Wii U a "portable gaming console" which makes us believe there could be some mix-up with the names they have provided.
