OP, Please fix this by add some explanation, or delete this, It confused peoples,  This pic from 2013 , it's a PS4 DS4 prototype controller. 

Looks basically like the DS4.

So, maybe they're using DS4 controllers cuz Sony hasn't finished developing prototype DS5 and devs are forced to use OG stuff.

Or

They really are DS5 prototypes that exactly looks like DS4.

Big turn off if it's the later. I don't like the feeling of the DS4 in my hands.

Isn't this just the leaked PS4 prototype? I'm pretty sure this is old. You can see it here https://www.justpushstart.com/2013/02/prototype-ps4-controller-revealed/

Your second photo is a PS4 dev kit and a proto type DS4.

As for the first pic and the DS5 (the second pic is a DS4 proto and a PS4 dev kit) here is the patent for the DS5 and a rendered mockup of the DS5.

DS5 is mostly the same in appearance but adds a mic. Is thicker. Triggers are supposed to have some tension tech to feel like pulling back the string of a bow and such. SO some sort of haptic feedback I guess.

The lead up to next gen is the best. People are hungry for every bit of information.

I like the crazy design of the console as a dev kit. Wonder what the retail one will be somewhat similar. I don't mind something a bit unique. I also like what I see of the dualshock 5. Familiar with some upgrades. I happen to really like the dualshock 4 though. Can't wait to get my hands on one next holiday season.

OP Fixed. My bad, busy with thanks giving and all that.

Please sony let the retail version look like the devkit console or better
