I'd expect that Rossi can win on any bike (e.g., Aprilia). Assuming no injuries, Rossi probably has several years of racing left in him. Even so, Rossi won't be able to race forever, he ought to get what he can while he can (rumor claims the dispute is about merchandising using his name, not about money BTW). IMO, Honda need Rossi more than Rossi needs Honda (though Daijiro Katoh may change that).
