Here's Lance's prediction- BikeRadar.com: Landis gets Lance's backing. In a nutshell:

"I think conventional wisdom is that he will lose, because USADA has never lost a case," said Armstrong, the guest speaker at an Aspen Ideas Festival health forum discussion on Tuesday.
"The arbitrators don't ever rule for the athletes. Quite frankly the system is set up against the athletes. ... Unfortunately for him, I don't think he did it. That's always been my position and still is today, but I'm not sure that's he going to get a fair shake in this trial."
