I have confirmed with Harley Davidson that there will be No Gold Key. Here is the email they sent me.
There was indeed a late change to the 2013 CVO owner package. The 2013 CVO owner package includes a CVO Collector Coin (which replaced the key) and CVO Gold H-D Museum Membership. The CVO Collector Coin is both model year and model specific and is only available to new model 2013 CVO purchasers. The 1-year H-D Museum Gold membership gives you unlimited visits for 2 adults plus up to 4 guests with each visit, 2 limited edition Museum dog tags, certificate for a free audio tour, 10% discount at the Motor Bar and Restaurant, Café Racer, The Shop and Online Art Shop, and more.
You should expect the H-D Museum Gold membership kit and CVO Collector coin to arrive within 4-6 weeks of your purchase.
