Here are some of the latest credible rumours passed on to Crash.net by sources within the Sepang paddock:

"Troy Bayliss may keep his seat at Ducati Marlboro, but the team are also known to be considering factory Yamaha rider Carlos Checa. Checa is a Marlboro favourite. The final decision on rider line-up will be made by Ducati and endorsed by Philip Morris."

"Should Ducati decide on a young charger, Suzuki's John Hopkins could be in contention. 'Hopper' is currently enjoying superb form in his third season of premier-class competition and would help the Bologna based company with the important US market. Ducati is also owned by Texas Pacific Group, an American investment fund."
