NVIDIA Asks: What is #Greenbox ?

While blurred out images are not foreign to me, especially when browsing Japanese websites, an interesting image popped up on my Twitter feed with the hashtag #greenbox. It is preceeded with the question of what could this upcoming NVIDIA Shield related object be. Is it a new device? Is it a gaming bundle? What is inside the box? Is it Gwyneth Paltrow’s head (#spoileralert)? Is it even a box? If you think you know what it is, Tweet with the hashtag #greenbox
