Its Nintendo's own fault really.
The system looks a lot like the Wii redesign they had shipped previously, along with their main advertisements for the Wii U, it is pretty easy for a non gamer to make the mistake that it is just a new add on/accessory to go with the long line of them that Nintendo has released for the Wii.
In trying to release a system that sprung out of the Wii's previous record setting popularity, they screwed themselves due to the brand's popularity dropping before the Wii U's release and not being different enough to seem like a new system. The lack of original games is the major death blow however.
