WarioWare guys make Rhythm Tengoku, Japan only?

Who said there's no Game Boy Advance games coming out this summer? Oh right, we did. Via Neo-GAF comes word of Rhythm Tengoku (translated Rhythm Heaven), a new rhythm game by the makers of WarioWare that's coming out August 3rd! The catch: that's for Japan ... there are no announced plans to release the title elsewhere. Nintendo, you had me at "rhythm-based mini-games by the dudes who made WarioWare." Where's the love?

Here's a scan from Famitsu with some additional images of the game.
