It looks...weird? That touchpad may even be a screen with the way it looks! It looks like theres a speaker under it so...could be!
EDIT: A trusted source (by trusted, i assume they mean developer?) has confirmed to IGN that it is an early prototype of the controller, so its likely different now.

IGN additionally noticed a possible button to the upper-right of the d-pad which could be the rumored share button, AND the glowing rod at the top of the controller which could be Playstation Move related. Hmmmm...interesting.
