Will these ever exist and come to Wii U?
Namco Bandai has filed for three different "Tales of" trademarks in Japan, according to the website, Hachima Kiko.
The three trademarks, Tales of Zestoria, Tales of Creales and Tales of Catastora all represent possible new entries in the Tales series. The last entry in the series to show up on a Nintendo platform was the 3DS remake of Tales of the Abyss.
Namco has yet to show interest in bringing the Tales series to any of the next generation consoles. One or all of these trademarks may be the entry in the series to now make the jump. However, as some of Namco's previous "Tales of" trademarks never resulted in anything, there is no promise that these will even result in a game.
