Inti Creates originally planned release for winter 2016
Back in September Inti Creates announced plans to release an Azure Striker Gunvolt anime in the form of an OVA. While it was originally planned for a winter 2016 launch, a recent update has it moving back a bit to sometime in January.
Inti Creates cites "various circumstances" for the delay, but it's still technically hitting the winter part of the plan. The OVA will be released in the 3DS eShop in Japan, North America, and Europe.
Here's the previously-released subbed promo:
Yoshinori Odaka (Cross Fight B-Daman eS, episodes of Tegami Bachi and Yona of the Dawn) is directing, with Shigeru Murakoshi (scripts for Garo the Animation and Knights of Sidonia) on scenario, and Masakazu Sunagawa (animation director on episodes of Saki and AKB0048) on character design and animation supervision, along with cast members returning from the game.
