Before settling on the largely-familiar design of the DualShock 4, Sony had experimented with a number of new controller ideas for PS4. One facet the company was mindful of was the placement of the analog sticks. Many shooter players have grown accustomed to the asymmetrical placement of both left and right sticks on Xbox 360's gamepad. Sony had to mull over whether or not they should follow.
"For the analog sticks, we did test having the analog sticks on top, since the Xbox has the left side on top [above the D-pad]," Sony's Toshimasa Aoki said. "Especially from the shooter teams--we got feedback that that's what they wanted. They knew that consumers liked the 360 for shooters."
