Chibi-Robo Photography came out on the Japanese 3DS eShop several weeks ago. There was some concern that the download wouldn’t make it west, but it does indeed look like an overseas launch is planned.
The OFLC has rated “Chibi-Robo! Let’s Go Photo!” – a new name, but definitely the same game. Nintendo hasn’t made an announcement for North America or Europe, but you can rest easy knowing that the eShop release will probably be coming over eventually.
