It appears that Trendy Gamers might have stumbled across the release dates for three fairly big PS3-only titles. After searching Best Buy for LittleBigPlanet Karting, PlayStation All-Stars Battle Royal and Ni No Kuni, three very specific release dates popped up for each title. LBPK was slated for September 25, 2012, All-Stars for October 23, 2012 and Ni No Kuni for January 15, 2013.
While all this information has neither been confirmed nor denied at present time, each release date seems specific enough to be at least somewhat believable. And despite the possibility of merely being placeholders, none of these dates seem too far-fetched for each corresponding title either.
