Last week, Crunchyroll News mentioned that 5pb's trilogy of visual novels/anime Chaos;Head, Steins;Gate and Robotics;Notes were being celebrated at “Science Adventure Matsuri 2012 Summer” this weekend. Reports out of the event are that the series will soon be a tetralogy.
The image that accompanied the announcement showed Shibuya landmarks, suggesting to some that the same might be related to "Delusional Science NVL" Chaos;Head.
Along those lines, 5pb. also announced that Chaos;Head will be ported to the PlayStation 3.
Chaos;Head and Steins;Gate visual novels have been adapted into anime, released, or soon to be released, in North America by FUNimation. A Robotics;Notes airs in Japan this October.
