Well I guess I can't be surprised that they're using the one layout that no one else has used yet: both sticks above, and the buttons down below. It certainly won't be confused with an XB1/PS4/WiiU controller.
That said, the lack of a D-pad seems to be a pretty big oversight. There's a reason why controllers have those buttons on a hard cross, as opposed to making them separate buttons. They're meant to be easy to shift among.
