Nintendo shares fell today in Japan in response to what's generally felt to have been a weak E3 press conference.
Its shares dropped 1.8 percent on Wednesday in Tokyo, compared to the 1.8 percent gain on the benchmark Nikkei.
The platform holder's shares had gained three percent on Tuesday in anticipation of Wii U's unveiling. Its shares have lost almost 15 percent since January this year.
Nintendo president Satoru Iwata told Reuters: "The device has to win support from within the family. So we have to show the benefits of the Wii U device from different angles in order to reach the mother, the father and the children."
According to prominent industry analysts, Wii U is currently missing a much-needed killer app, pricing could yet be an issue, and third-party support for the platform isn't very encouraging.
