The Hyperdimension Neptunia series has been a hit for Idea Factory and to some extent NIS America. Have you seen how much copies of the PlayStation 3 game cost on eBay?

Hyperdimension Neptunia Mk2 with its new character and Twitter-ish interface is available in Japan now. NIS America announced they would localize the sequel for North America and Europe with a targeted release in spring 2012.

What’s next for the Gamindustri and Neptunia series? "Next year will be the year of Neptunia," Damien Urvois, Business Development Manager, teased to Siliconera.
