Raiden IV gets limited edition with bonus soundtrack

As if we didn't have enough trouble overcoming the elation brought on by the impending North American release of Raiden IV, Joystiq has now received news that the game will also be available in a limited edition. The limited edition will come in two flavors, one exclusive to GameStop. The vanilla, non-GameStop edition will include a bonus soundtrack CD, while the GameStop edition will include the soundtrack and a "secret file," which we're told will include "concept art, boss and enemy data, game strategies, etc."

Also, the press release notes that the game is releasing in September, rather than the previously announced August release window. We suppose one more month is a small price to pay for a spiffy limited edition.
