Last week, glaucoma various reports about Tales of Xillia getting it's own anime reached the net due to an accidental leak about the Viva Tales of Magazine. With the release of the magazine's cover, however, there is no sign of a Tales of Xillia anime.

So, what exactly happened here? As one of our mods, cutepresea mentioned, it might have been just a little mix up between Tales of Xillia, currently the series' most popular game, and Tales of Symphonia The Animation's United World Episode (probably because of the hype with its release).
