Google’s affiliate policy has not been changed. This means that your approved affiliate AdWords ads will continue to run on Google.com. Please be assured that we have no current plans to completely block affiliates from AdWords. If we do make any changes to our affiliate policy, you’ll be notified.
The word 'completely' is a bit worrisome. My opinion -- If a change to policy is made, please hold off until after christmas at minimum, or there will be HUGE uproar from a large segment of advertisers.
