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? 

As far as I know the DS4 still uses the Bluetooth 2.1 protocol.

There have been A LOT of Bluetooth improvements over the last years. Bluetooth 4.0 - 4.2 only drain a fraction of power, which should improve battery life. For Bluetooth 5 there will be improvements in all areas (power drain, range, speed): http://www.techradar.com/news/networking/bluetooth-5-everything-you-need-to-know-1323060

I really hope that the new DS4-model (transmitter) and the PS Neo (receiver) both support Bluetooth 5 or at least 4.2: https://en.wikipedia.org/wiki/Bluetooth#Bluetooth_v5

P.S.: Damn, according to the FCC document, it it still Bluetooth 2.1 + EDR? WTF? That is still tech from 2007, which was already a shame when the PS4 released in 2013! Bluetooth 4.0 (aka Bluetooth low energy) is available since 2010: https://en.wikipedia.org/wiki/Bluetooth#Bluetooth_v4.0

I hope that this is only an enhanced model for PS4 and that the Neo gets a "DS4.5" with newer bluetooth specs.
