Nintnedo president Satoru Iwata told a meeting of investors that no retial information for the next generation console will be announced until 2012.
He said: "Since the Wii U we showed you at the E3 show in June was still in the development phase without very specific proposals on the software titles, we are going to announce the release date and the price next year when we are able to explain the specific proposals."
Iwata also spoke about the recent price drop for the DS handheld system, and the impact this would have on consumer trust once the Wii U launches.
He added: "With regard to the influence on the Wii U, what we have to take most seriously is that the price markdown could damage the trust of the consumers who bought the Nintendo 3DS just after the launch.
"I feel greatly accountable for it. Our decision of the price markdown this time has a side effect that, at the launch of the Wii U, people may feel that the price might drop in the near future if they wait. What we will be able to do to recover the consumers' trust before the launch of the Wii U is very important to us."
The Wii U is expected to be released in time for Christmas 2012.
