Now those hucksters over there at 9to5Mac (for shame!) are claiming a tipster has told them it’s a battery release latch. Well, if Apple knew nothing about designing hardware, and the MBP didn’t already have a battery release latch, I might have believed it!
Seriously, a battery release latch there would be calamitous. And it’s not a dock thing either, damn your eyes! Just wait till tomorrow, stop speculating!
