Satoru Iwata has talked about the possibility of bringing Miiverse to 3DS. Speaking with Nikkei, Nintendo's President said that the company's 'social network for gamers' would enable them to make a game like Animal Crossing: New Leaf even better.
"If there was Miiverse on the 3DS it would probably be something amazing," said Iwata. "If Miiverse and Animal Crossing were integrated together, we'd have the chance to create something even more awesome [than what is going on now]."
In the same interview, Iwata commented on integrating Miiverse with smartphones. "I can't make any concrete statements about when it will be available yet, but it won't be far away."
