As a Wii U fan, I know where the other posters are coming from with that investor's meeting stuff. They didn't offer any relevant game plan to get the Wii U moving & shaking and instead diverted focus to things happening far in the future, like QOL and even future hardware. The focus was not the short term. It was disappointing to say the least.
I wouldn't count on the production costs of Wii U going down significantly any time soon. That tends to happen when many units are selling and they're able to place larger manufacturing orders.
I do, however, feel that a Mario Kart 8 bundle, and/or a price drop to coincide with its release could be a major shot in the arm. I even think stockholders would understand a loss if they do this and the system starts turning around. I just don't have the faith in Nintendo to do it. It's like they have an open wound that they won't treat. They just hope it will heal soon on its own.
