I dont think there is any chance dana stays to be a figure head. His ego is far too great for that.
Joe rogan is only staying in place if the same owners and management stays in place. He had actually left the ufc gig when dana and co took over. He stays on as a favor to them. Much prefers to do his fight companion. He's been pretty forward about it. They sell he goes. Too bad mauro has a job with the wwe now. Having fight companion and mauro/bas at the event would be amazing.
