There's a rumor circulating around the wild wild web right now that says Square Enix may not be looking to offer Kingdom of Hearts: Birth by Sleep via digital distribution on PSN, possibly adding insult to injury for all PSP Go owners out there. The rumor originated from Twitter user Magunus, who apparently attended a recent PlayStation event in Japan (we can't figure out which event this is referring to, and there's no mention on the official Japanese blog) where a clerk confirmed it, citing "copyright issues."
This strikes us as odd not only because of the tenuous nature by which this has been reported, but because a lot of Disney Interactive's titles have been made available via digital distribution in the past. We've contacted both Square Enix and Disney Interactive about this and will be sure to let you know what we hear back.
