Dennard scaling stopped years ago. There's definitely room at the bottom for different topologies — probably 5–10 generations worth. But! These are probably 5 year steps, not two year steps. Also, there's just as much room for the improvement of HW design as there is in peeling off SW abstraction layers above the HW.
