Not sure mate. Maybe the best commercial outcome for the future of MotoGP would be a reconciliation. If, when Rossi finally retires, it's still all bitter and twisted, then I don't think that would be good for business.
Best outcome for Dorna is probably for Valentino to win the title and retire. I don't think either MM or VR is the forgiving type, and I am not sure about either MM's acting skills, or the likelihood of him showing discretion in future track encounters with Valentino.
