The last we heard about it, the game was slated for a release sometime in the summer of 2013. But now, Namco Bandai Games has posted a page for the title which gives us an exact release date: June 25th, 2013.
Of curious note is the tab marked "retailers" on the page, as it only lists Amazon.com and GameStop as carrying the game. Given that other titles show a wider range of stores, we are left to wonder whether this will only be a limited release (and if it will even make it to Canada). More info on that as we get it.
Thanks for the tip, Magnet Man and WetCircle!
