When it comes to the analog sticks, Aoki continued, "We did test having the analog sticks on top, since the Xbox has the left side on top. Especially from the shooter teams - we got feedback that's what they wanted. They knew that consumers like the 360 for shooters."
The Dualshock 4 is a big leap above the Dualshock 3 and is above and beyond the greatest Playstation controller Sony has created. Some of my favorite new features include the headphone jack for listening to actual game audio, the touchpad, the larger overall comfortable design and the much improved triggers.
However, do you think it would benefit Sony to offer another iteration of the Dualshock 4 at retail, one that uses Microsofts asymmetric analog stick placement? I think alot of Xbox fans (myself included) have gotten accustomed to the placement and find it very comfortable and natural. I think Sony would be able to draw in a larger portion of the Xbox crowd if it offered this as a secondary controller option.
