Iwata Says:
"As for the details of exactly what it will be, we have decided that it is best to let people experience it for themselves at E3. So I won’t talk about specific details today, but it will offer a new way of playing games within the home."

"We would like to propose a new approach to home video game consoles. It’s difficult to make 3-D images a key feature, because 3-D televisions haven’t obtained wide acceptance yet."

"3D not a focus for the system", says CEO. "System being released because developers having hard time delivering surprises on Wii."
Whatever surprises Nintendo has in store for the system, 3D may not be one of them. Iwata also said that "considering that 3D televisions have yet to spread widely, making 3D into a central point of the system would be difficult."
sourceSo I wouldn't really count on 3D being a feature, but you never know. They don't need a 3DTV with screen in the controller afterall, but that kinda steps all over the 3DS considering a majority of people play their handhelds while at home even if intended to be played when away from the house.
It's possible that a 3D Cafe controller could complement a 3DS and really push Nintendo as the innovators of 3D in the home especially if it allows a much cheaper way for the family to view 3D TV & Movies with their own personal screen w/o the use of glasses.
....Now that I think about it, that would be a major blow to Sony and the overly expensive 3DTV movement. That could be a really good play on Nintendo's part, especially if they include a modified (no royalty) Bluray Drive and allow the end-user to pay the licensing fee to play Bluray movies.
