It's true! As the title says, supposedly an announcement was made by Aki Takanori, the president of Good Smile company at AFAX. I discovered this article on Facebook, thanks to www.Vocaloid.net people. I'm REALLY EXCITED for this so I hope it's true, because it would be really awesome to see more Black Rock Shooter anime. And if I see the first OVA at Naka-kon this year, I'm going to buy it, no matter what! (unless it's ridiculously high-priced XD I'm a poor college student now.)
Anyway, keep an eye out for it and if you know anything, please inform me so that I may share the news with others as well!
Info from here.
Thank you for reading and have a great day!
