Angel Beats! visual novel announcement will be “after summer” via animenewsnetwork. Summer in the northern hemisphere ends in August so the earlier we’ll get it is September.
Baba said in February that fans could expect information before this summer.
An Angel Beats! game adaptation has been a topic of discussion among fans since Maeda revealed a possible adaptation in November of 2010. After two years with little to no updates, Baba re-acknowledged the possibility of a game adaptation on Twitter last October, but stated that the project is not yet at the stage where it can be announced.
