That somebody is retailer JB HiFi, who have taken it upon themselves to stock the game in limited quantities for sale exclusively through their brick-and-mortar stores throughout Australia.
We liked the game quite a lot in our review and found it to be essential playing for the shooter crowd. Even more so if you're into weird anime stories and giant exploding things.
A release date isn't set, or advertised at least (the Web site is content with a big "coming soon!" badge), but you might want to hit up the JB HiFi site to find out which stores will stock Treasure's treasure and badger them accordingly.
