I think it depends a bit on where you're from.

If you're from the United States, then this definitely seems like the biggest doping scandal in the history of bike racing. The Tour is the only race most folks have heard of here, and Landis is from the US. This may be the end of popular media coverage of bike racing here, too, with Lance retired and the Tour turning out to be a big dope-fest.

But if you're from Italy, the biggest story will probably still be Marco Pantani getting booted from the Giro, and eventually dying from a cocaine overdose. Books have been written about it, tv news shows covered it, and a movie came out this year.
