This leak is becoming more and more credible by the hour. The guy who sent the original image has been confirmed through multiple sources to work for a French advertising firm, which has had a history of working with Bandai-Namco, who is helping develop Smash Ultimate.

Mind you, he was basically doxed by 4chan anons, so yeah it's pretty much confirmed by this point, though the possibility that he was merely the fall guy for the one who actually took the picture is still there.
