I think he's done when the calendar runs out. Both he and Burry have signed on with Specialized for next year. Burry's tight with Sauser and Todd's going back where he started too.
It will be interesting to see what GT does.... Now that they are part of the Cannondale Sports Group umbrella. They also let Kitner and Bryn go so there must be something in the works. I wouldn't doubt it that we see a Pro Tour road team riding GT again soon. I'm sure they'll be signing somebody for XC and or downhill though. Their upper product is to good not to be represented by top racers and that goes with their past.
Needed: 26.8mm XTR seatpost, blue GT/Grundig Jersey.
