Where is the verification of the rumours you mentioned, onion?
Brad's LinkedIn, we've been over this. I'm guessing you don't have much experience with the professional world because Brad's profile would not indicate his term was over in March 2016 unless he left; it would say "-Present" like Kyle's.
Admittedly this is only evidence that Brad is gone, it doesn't necessarily mean that no one will replace him. But I don't think there's any reason to doubt the sources for this news, given that they are right so far.
