Katsuya Eguchi, the creator of Animal Crossing has shared the following regarding the upcoming 3DS version of the game:
"To those Animal Crossing fans, I just would like them to know that there’s progress and we should be able to offer a new download movie soon. As for features and specs of the game, I can’t go into too much detail, but players will be able to arrange their furniture the way they like, and we’ll be offering new networking experiences."
Very little has been given away about Animal Crossing since its unveiling in 2010, so hopefully we'll hear more soon.
