Demonstration of Swapnote, the 3DS’s new messaging app releasing soon. It’s what we always wanted from PictoChat: an application on your portable for sending 3D messages, photos, and even bits of audio to your friends online. It took seven years, but it’s finally almost here.

This came out in Japan today as Itsuno ma ni Koukan Nikki, and releases this week to Europe’s eShop (along with Game Boy’s Tetris!) as Nintendo Letter Box. If we’re all good little girls and boys, maybe it’ll release in North America this week, too, just in time for us to send notes to people in our Friends List for the holidays.

Along with being able to pass messages to your friends (apparently there’s a mass send function, too) and people you encounter via StreetPass, you’ll also be able to just save your notes as a personal diary.
