Famitsu.com has posted a report about Namco Bandai's upcoming Tales announcement. The report says that the new game is a "mothership" title. This would put it in the same class as games like Xillia, Vesperia and Graces. It also means it's not a remake akin to Tales of Innocence R, and it's not a side-offering like Radiant Mythology.
Namco Bandai has not announced a platform or release timeframe for the new game. The announcement will come on June 2 at the Tales of Festival event. Tales Members can watch the event live. Namco Bandai will also be airing commercials for the new game during the Hey! Hey! Hey! broadcast on Fuji TV on the 21st and 28th.
