It shouldnt change anything. It's an EU monopolies ruling to avoid one single business controlling MotoGP AND F1. Dorna I would imagine have a 5-10 year plan for the sport which essentially won't change. Even if the chief personnel change at Dorna ( if that's what they continue to call it ) which is by no means inevitable 'if it ain't broke they ain't gonna fix it' . The sport has grown globally, the only changes I can see at all might be a more international flavour, ie. less spanish riders which would be a good thing.
