MM Cal is indeed going to Ducati. Good move? In terms of £££ yes, because usually a factory rider gets more money than a satellite rider. In terms of bike/team, the answer is probably no.
In the past 6 or 7 years Ducati have only won one world championship, with the much-underrated Casey Stoner on the bike.
In fact, Stoner is the only person who managed to win a race on the Ducati in that time! Rossi and Nicky Hayden, both ex-world champions, couldn't manage to win on the Ducati.
Set against that, Ducati have been bought out by Audi and have received money and hopefully some Germanic efficiency. Plus Cal is not lacking in guts, so if anyone can make it go, he's probably the one to do it. We'll see.
The riders tend to be tough boys. Jorge Lorenzo broke his collarbone in a crash earlier this year, had it operated on and 48 hours later rode in the race...
They had to peel him off the tank at the end of the race, but he did it.
TV coverage can be a bit spotty. Eurosport 2 on Sky has practice and qualifying, but not the live race, the BBC has that. As WM says the Beeb commentators are pretty good.
