I still wonder wtf the Treehouse is... Like is it just a developer interview or what?

Treehouse is the division of Nintendo US that handles the importing (especially localization) of Japanese titles. They were created because Nintendo of America felt that the quality of localization for Japanese imports was very poor. For marketting, whenever there would be things like interviews with developers and such in Japan, they handle that as well (as a Japanese language interview isn't much help for most Americans) which is why they are in the E3 stuff. Think of them as the liaisons between Nintendo Japan and Nintendo US.

Edit - Kotaku (yeah, I know) did a write up about them not that long ago.
