Yeah, you're right, those aren't the same controller. The alleged DualShock5 in the top photo has a flat top, while that other one in the 2nd pic has a tiered design on the top. The DualShock 5 in the top photo basically just looks like DualShock 4, so much so that it might just be a DualShock 4, I'm not noticing any differences. Handles are shaped the same, as opposed to the thicker handles that we saw on the alleged DualShock 5 patent a couple weeks back. The L1/R1 and L2/R2 buttons are shaped the same. The touchpad is shaped the same. The D-Pad is the same. The Options and Share buttons are still too small.
I believe that the controllers in the top pic are DS5 controllers, or maybe prototypes. They are almost identical to the DS4 but the USB port is higher up, meaning that if it has a light bar, it's probably below that USB port or maybe integrated into the touchpad, like the second design of DS4 controllers.
