Nothing you presented comes to the conclusion that it's "highly" likely he won't be back. It just says there's a chance he won't come back.
Sorry if the media aren't falling in line with your weird "cheating" stance. Cora wasn't involved in cheating here, but you won't recognized that. Cora was a fall guy in HOU because he was no longer with the organization. All the leaks that came out have stated that the Astros cheating began before Cora was even there. That would just require some critical thinking and reevaluation on your part.
