First up is the box. Im not sure when they made this change but my C70 didnt have the notches on the box for easy opening. I remember kinda having a hard time separating the box when I first got my C70.
Second thing I noticed was the C80 units have a few screws missing. Im not sure if this is something they just started doing, but I exchanged three C80 units at Gamestop yesterday because me and the manager thought it was a flaw but all 3 random units had the two missing screws.
Here are a few shots of the back cover and unit. Im not sure if anything is different but maybe someone whos more familiar with the insides may notice something.
I did noticed the serial # on the rear sticker is now printed in white as opposed to black:
