So Nintendo have announced their E3 plans. No conference, but they are having Smash playable at Best Buys across the US, a Smash tornament, a nintendo direct and a "tree house" at E3 (just a place for show goers to go see the devs themselves.

Is this a mistake? Should Nintendo be having a conference this year??

I want to know what is that TREEHOUSE thing 

"This year, Nintendo will offer fans a deeper look at Nintendo's biggest games of E3, with information directly from the source. The "Treehouse," the Product Development department at Nintendo of America, will provide in-depth game demos live and unscripted from Nintendo's booth. This new program will be live streamed during all hours of the E3 show. Fans can get settled in, open their browsers and experience the Nintendo games at E3 like never before."
