The picture above is widely regarded to be the closest fan-made concept to the real thing. It's not the real thing, but I wouldn't mind if it was... it's actually pretty sleek.
This news comes in via Kotaku, who also state that the controller is rumored to have 8 buttons. No mention of triggers, but being that they're THE standard for hardcore shooter fans, they'd be kind of dumb not to have them.
During a recent meeting, an analyst asked Iwata for his opinion of tablets. Iwata acknowledged their appeal, drawing comparisons between the Nintendo DS's touch interactivity.
"Whenever we make a new game console, we've done it without throwing away buttons and the directional pad," Iwata said. "The reason for that it's better to have them, because buttons and directional pads benefit gameplay response."
"Taking this into account," Iwata continued, "Nintendo isn't planning on completely ditching buttons, nor is Nintendo thinking of taking tablets as they are today and implementing them in a game console." -----------
Exciting stuff! A controller with buttons! WHO COMES UP WITH THIS?! :D
