Nintendo has confirmed retailers listing Wii U games around the $100 range "are using fictitious prices".
Retailers such as Amazon and GameStop have begun to list Pikmin 3 and Lego City Undercover at the massive price point, and in a statement to GameSpot the platform holder confirmed official pricing details have not been revealed yet.
"Retailers are beginning their presale activity, but given there is no official software price, they are using fictitious prices," it said.
"When software pricing is officially announced later this year, I am sure retailers will adjust their websites to reflect the true price."
Nintendo hasn't officially dated when the Wii U will be available, but recently Amazon Germany listed the new console for a December 21 release.
