Well, not really, but he might return, and it could save Georgia. Given that the race was informally known and popularized as Armstrong's Tour de France preparation, it seems only fitting. It would definitely turn the Tour of California into an absolute circus as well -- something I'm actually not looking forward to.
The rumor has been swirling for awhile and was given greater credence when Dirk Demol returned to Astana. It's unclear what the motivation here is -- is Armstrong mad enough at the TdF organizers for excluding Astana? Is he a little too bored on the MTB circuit? Who knows, though I do feel a little bad for the other Astana riders knowing that they will have a different spotlight shining on them.
