It's probably not a gimmick or an innovation. It's just a touchpad, after all, and I doubt it will be used in most games, except perhaps for menu systems. We'll have to wait and see.
Personally, I think of a gimmick as something that's focused on in order to increase sales, and I just don't think the controller is going to be much of a focus. The games themselves appear to be the point of the PS4, not a new control scheme.
If anything from last night could be described as a gimmick, it would probably be the Share function.
