Those are pictures of Hatsune Miku and Future Friends Project Mirai, the Vocaloid idol’s debut 3DS game. Sega has it slated for release on March 8 and the limited edition includes a nendoroid petit Project Mirai style Hatsune Miku.
All of the CG models in the game are designed to be like Good Smile Company’s figurines. In addition to Hatsune Miku, Luka, Rin, an Meiko are also in Project Mirai. Selectable songs include: My Time, Piano*Girl, Sing & Smile, Tricolor Air Line, Daughter of Evil, and LOL Lots of Laugh.
When you’re not tapping A and B to the beat you can hang out with Hatsune Miku by selecting the "My Room" option or set up augmented reality desktop concerts. While Miku and friends are dancing you can take 3D pictures.
