If the other teams don't build such an organisational structure, then I suspect Ducati's advantage will survive the forthcoming technical regulations changes.
Ducati also inherited the VR46 academy when they signed up the team. Smart move, and it looks as if VR46 are coming even further into the arms of Ducati.
If Ducati did make a Moto3 bike, which Claudio Domenicali said he was confident would be very fast from the start, then that would make an even stronger pipeline. Of course, they may be too busy moving into the motocross market, but CD did say 'never say never'.
