We've gone from joystick and a button, to dial, button pad, and roller ball and on into motion sensing. Do you think it would be interesting to see more buttons? It was once suggested by random talk that at the least, two more buttons could fit on a controller. On the rear/bottom (for example a ps3 controller) as lower triggers, rear/center on the 360, or touch sensitive/more buttons on a wii controller. What do you think? Is is stupid to keep trying to add buttons, as someone thought before we had shoulder buttons, or is there change coming in the far future that advances 'motion sticks' and such.
