Also new factorys are going to be opened to produce more yeezys according to Kanye on twitter.
Its seems these are indeed a photoshop, but something similar is due to arrive soon.
According to Complex these are not the actual sneaker, but a mock-up intended to give you a better idea of what to expect when these arrive.
More info on March 26th at the Baltimore Sneaker Show 2016.

I was one of the lucky ones that got a normal sized box. Ive seen a few pics where some have large box while others have normal sized boxes.
I believe someone here said that any size from 10.5 and above would come in a large box.
