Coming from a Kotaku interview...
"I think the Wii U is a brilliant console that offers a lot of innovation and possibility for new types of gameplay. However at this current time we don't have any development plans to make any Tales of games for the Wii U." - Hideo Baba
The system is SO brilliant that Baba can't even fathom the idea of bringing a Tales title to the Wii U! Man, what a compliment!
