Fender.com shows this as unique to the Deluxe 5-string. A compound radius (9.5 - 14 inch) asymmetric neck. I'd be interested to hear your views on playability and feel compare to the standard 9.5 inch American Standard. GAS will get the better of me one day and I may change from Standard to Deluxe. It'll probably be a while though - here in the UK they're still selling 2010 Spec instruments as new.
