Looks like GameStop let the cat out of the bag a little bit early. You're now able to preorder Dragon Ball Fusions at GameStop, even though Bandai Namco hasn't even confirmed the game for localization. I guess they'll have to come out and do that soon!
Also, for what it's worth, we have an inside source that has told us that Bandai Namco is indeed localizing the game. I wouldn't tell you that unless the info is extremely trustworthy, so take that for what it's worth.
