Project Sora is No More
Kid Icarus Uprising studio dissolved as of June 30.
Kid Icarus Uprising developer Project Sora has been dissolved. Access the company's webpage, and you'll now see a message noting that the studio was closed as of June 30. The website will close on July 31.
Project Sora was formed in 2009 by Masahiro Sakurai, with investment by Nintendo, Sakurai's Sora studio, and other parties. The studio developed Kid Icarus Uprising as its first, and apparently only, game.
Sakurai is serving as director of the 3DS and Wii U entries in the Smash Bros. series, which are being developed by Namco Bandai.
