"Wii-no-Ma service is available only in Japan at the start, but the overseas deployment is under planning in the future," said Iwata.
Iwata also added that the Japanese content may find its way to our shores, saying
"As Japanese videogames, anime or manga are very favoured all over the world, we also anticipate a great possibility of same spread for video programmes."
