This is clearly a business move made by Ducati, and one which has my support. I think its a good idea. They will now focus on the Motogp prototype 1000cc bike and with Rossi on board what a great chance they have of winning that title. I dont think the move is due to covering the costs for his wages, I really dont. I also dont think it will have an impact on sales, especially if they win next year !
Now, boring as you may say but Motogp is where riders want to be, it is THE biggest stage a rider can participate in and prove themselves as the best out there. More riders are planned to take grid slots to add further competition.
I love Haga and he is one of the best riders iv seen, and having watched all races last year, in my opinion despite losing out to Spies, he was the best rider for 2009 and but for a couple of moments of bad luck, it could very easily have gone his way.
However he probably wont compete at the front anymore and Fabrizio just hasnt made it, so why dilute resources and funds in what is thought to be a second rate competition to motogp, when you could throw everything behind the 2011 cause.
Smart move, both financially and from a race perspective. Ducati wont miss WSBK, and they are going for the throat of motogp.
