From the upcoming anime.

Dengeki PlayStation reveals this week that Namco Bandai is developing a PS3 and PSP adaptation of Accel World. The game is said to be a strategy game showing your Duel Avatars facing off one-on one, but that's all we know at the moment.

Accel World originates as a February 2009 light novel from Reki Kawahara and Dengeki Bunko. A manga adaptation began in 2010. An anime is scheduled for April.
