of all the games that came out only in japan, i think this one it's perfectly expendable, and i really don't see the reason or point of localizing it. The genre itself doesn't work very well with home consoles, if you really wanna play an on-rail shooter, you go in a nearby arcade and play some House Of The Dead, Time Crisis, Ghost Squad, whatever. the 360 doesn't even have a light gun (the Wii would have been a better choice, it's pointless playing this kinda game with a normal controller), it's a moefest, the plot is plain silly, not really a bad thing as story doesn't matter at all for this genre, yeah, but doesn't help the game in being "appealing" outside of Japan.
Don't mean to bash it or anything, but i think it's kinda pointless to even hope for a western release.
i'd prefer to see something that's more "new" to western audiences, like VNs, still niche stuff, i know, very niche stuff. speaking of 360 games, i would like to see translated Stein's Gate, so i can give it a go, but again, is kinda pointless to even hope. Too bad.
