Edmunds.com has an estimate up on their website of $68,250 for the RS5 and a target launch of 'Fall 2010'.
Also on Fourtitude, one of the members confirms with a reliable source that the RS5 will be coming as a 2012 model. So most likely coming in 2011 as a 2012 model? I dont know what to make of this info. Footie, maybe you can help clear up some of this.
