Widely expected, Tales of Xillia 2 was indeed confirmed as the name of the series' next sequel at the Tales of Festival in Japan today. The word comes from producer Hideo Baba himself.
That trailer introduces the new world of Tales of Xillia 2, which does reflect a departure from the sword-and-sorcery motifs of previous entries in the Tales series. There's also this one-minute look at the game's combat.
A Japan release is scheduled for the end of this year; a specific date and price will be announced on June 27. The game is for the PS3. There's no information on any western localizations. The first Tales of Xillia was a Japan-only release.
