The newest patents published by EUIPO reveal two possible designs for the 2020 Galaxy Fold models. One design is almost identical to the current Fold, except it has smaller notches. The other one features a horizontal hinge that enforces a form factor similar to a handheld console. It also has a centered upper notch and the outer screen is considerably larger.

The flat fold of that render is not possible with the current screen tech, why bother doing a render knowing that it won't reflect the end product?! I believe I've seen more than one impractical render from these people.
