Tour of California moving to May for 2010

The Tour of California has announced it will be held May 16-23 next year (see e.g., Velonews -  Amgen Tour of California May 16-23 ).  Good and bad news in this.  The good news is the weather will likely be a lot better than the February time slot.  Bad news is this competes with the Giro and it is unclear what riders/teams will come.
