Granted, it's only March, but this might be the most hardcore music controller released in Japan this year. That is, if it's released.
You are looking at a dedicated controller that's designed for playing Sega rhythm game Project Diva and... that's it. Dubbed the "Hatsune Miku -Project DIVA- Dreamy Theater 2nd Dedicated Controller", it will be available for pre-order from Japanese peripheral maker Hori. It's priced at ¥29,939 ($362).
The controller reproduces the experience of playing arcade game Project Diva at home on the PS3. But only if enough pre-orders are placed will the controller go into production. With the game's rabid fan base, that is entirely possible. Pre-orders start on March 22, so mark your calendars. Or not.
