You know what would of been really cool in my opinion?
If Sombra's been in the game since the last patch, and that's what the whole "Whoever has the information has the power" thing is referring to, that whoever finds out how to play her, gets to use her. Of course would only work in QM though.
I mean, I'm sure that's not it since we haven't seen a single thing of her, but still, JUST SAYING, since this timer seems to have led to nothing at the moment.
EDIT- Although apparently the PTR just got updated, so maybe...?
