According to Harada, in an article on 1up.com, he said that the 3DS and WiiU Tekken games are being created with the casual audience in mind, while the PS3/360 ones are for the typical, hardcore Tekken audience.
Not only that, but as more proof that it's on the back burner, he says they haven't even assigned people to start working on it yet.
What about Wii U? Harada laughs, "For Wii U, at the moment, the core members aren't really assigned to that yet. We have a different group outside the Tekken Project within our company that works on advanced technology. So that section is currently evaluating the hardware and the specs, and what would be necessary to create a Tekken on [Wii U]. Once their evaluation and research is done, they'll kick it to us and we'll start laying out the specs for that. But we're not at that point yet."
So, knowing that it will probably be a simplified version of the game (I'm imaging moves being available right on the touch screen, instead of having to memorize inputs), without Harada's full attention, are you still excited for the Wii U Tekken?
