KBB and edmunds base their prices on actual trade-ins and sales and auctions. There probably isn't enough data to provide pricing yet. It happens with every new model.
Only way to know at this point is have a couple dealer's appraise it.
Another thought is look to see what the best deal is for your model & options new and take off $3000-6000 depending on your mileage. I know that lacks precision, but what can I say. What would you pay for your car versus a brand new one?
