There's no proof the sun will rise ever again, but I'm certain that it will.
Just as certain as I am that a CEO doesn't abandon his gravy train without any advance notice, unless he's thrown out on his rear. And there isn't a shred of proof to show that he wasn't fired.
Say what you will about Joe - at least he'll forever get credit for kicking Matt to the curb. Best thing he's done as CEO, imo.
