In the same vein as the upcoming SAO film, Accel World, another series by Reki Kawahara which in a way shares a universe with SAO, will be receiving a new anime film called "Infinite Burst".
Accel World originally had an anime series in 2013 that ran for 24 episodes, and aside from a couple of OVAS and other misc. animations, "Infinite Burst" will be the first major anime project for the series in years. Also like the new SAO film, it will have an original story written by the aforementioned creator, Reki Kawahara.
