Why are you guys talking about the controller as if it did not change?
It has wider to fit a share button and also has the touchpad on the front and the big ass light from the Move sticks on the front of it. Its changing quite a bit.
The PS3 pad was too small, button travel too small, shape of the R2/L2 buttons was poor.
I had to put the gel tabs on the sticks and trigger grips on the pad to make it usable. Xbox has the pad design nailed imo.
