Performance Designed Products, or PDP, claims to have "no knowledge whatsoever" of the official Wii U release date.
Responding to rumors that the gaming peripheral-maker inadvertently "leaked" the Wii U's release date during a trade presentation, Senior VP of Sales and Marketing WIlliam Otte defended "it is not possible for PDP to have 'leaked' this information" due to the fact that they, themselves, supposedly don't know it.
"During PDP's presentation of our fall line of gaming accessories to customers at a trade event, we stated that our Wii U accessories would be available at launch. Much later in the presentation we showed our Epic Mickey 2: The Power of 2 accessories for the Wii and confirmed that the Wii accessories will be in stores by the game's November 18 launch date," Otte explained in a follow-up with Kotaku. "Connecting the Wii U launch and Epic Mickey 2 peripheral launch dates is inaccurate and false. PDP has no knowledge whether this is the official Wii U release date or not."
Given that Epic Mickey 2 is set for a November 18 release also, it's possible that the original statement was a slip-up or maybe heard wrong, but there's also a possibility that they are using it as a cover up. Who knows, maybe the Wii U is releasing on November 18th and Epic Mickey 2 will be one of the system's launch titles.
Nintendo maintained silence on the rumors, only saying, "We have nothing to announce at this time". It's likely Nintendo will wait until their September press event to make any formal Wii U announcement. The invite-only event is set to take place in New York on Thursday, September 13. It will be hosted by Nintendo of America president Reggie Fils-Aime and address "how the Wii U will change the future of gaming and entertainment."
