I doubt we will see a direct soon. They showed alot stuff outside of an direct recently (Twilight Princess gameplay, Pokemon Sun and Moon, Pokken Gameplay). If they wanted to do a direct soon, they would probl didnt showed that stuff outside of an direct but included it.

3DS also has some staffs that could be shown, I definitely expecting one ND before E3.

Well looks like you were right
