Nintendo faces a massive task in educating consumers about what exactly its upcoming Wii successor, the Wii U, is capable of, Katsuya Eguchi, game designer and manager at Nintendo Entertainment Analysis and Development has told Edge magazine.

Asked if Nintendo faces similar challenges posed by the 3DS, in communicating the Wii U's unique qualities, Eguchi said: "You're absolutely right, those are just some of the huge challenges ahead of us - getting people to really understand what Wii U can offer.

"We have some experiences here right now - with 'Chase Mii' and 'Shield Pose' - and we have a great opportunity to give people time to play the games, so we'll take advantage of expos, conferences and in-store demos, but we really want people to understand how the TV screen and controller screen interact and how that changes the experience. And we've come up with a variety of uses. But you're right, we can't explain them all, and I don't even think we've thought of them all. I'm sure there are many uses that haven't been thought of yet."

Wii U is scheduled for release in 2012.

Despite a strong launch, Nintendo's 3DS has so far struggled to build any kind of sales momentum - not helped by a lacklustre line-up of software. It remains to be seen if a strong end to the year will convince consumers they need the 3D handheld.

A similarly lukewarm reception to Wii U could spell disaster for Nintendo, which has seen its hugely successful Wii console lose its hold on the games market in recent months.
