Super Street Fighter IV producer Yoshinori Ono has hinted there's far more to Wii U than we've seen so far.
What we saw last E3 is not a reflection of everything this console is able to offer. We have been trying the development kits and some of its new characteristics will improve its possibilities. It isn't something like Kinect or similar accessories, it's something different.
I can't tell you more about it because, if I do, Nintendo will send assassins to finish me! (laughs) But let’s say that Wii U will be a console with so many and unique possibilities that it will be difficult to show them in the box they are going to sell it or to be published by magazines and other mediums.
Ono's final comment about "unique possibilities that will be difficult to show" echoes comments about the 3DS before it was released, but what do you make of his — admittedly vague and twice translated — comments?
