this could just as easily be a very minor redesign to improve analogue rubber abrasion or battery life or sth

From the FCC documents it appears the Bluetooth antenna is getting an upgrade. Why? 

And why after all the different versions of the DS4 with the same serial number, change it to version number 2?

It must have some redesigned elements to up the version number.

Makes sense to have a better controller ship with the better NEO PS4 console. Why ship the NEO with the busted old DS4?
