I would think there'd be some small further loss John, but given that the best examples that have been around for a while like Panasonic-Sanyo and BionX batteries with very little loss reported, I don't think it will necessarily be serious. When questions were asked about the BionX battery in here some while ago, some responses indicated no readily detectable loss in range at over two years old. I've also never seen complaints on the types of Panasonic units using lithium for more years than that.
50cycles may also have some relevant information, since they imported the Panasonic Will and Honda Step Compo Li-ion folding e-bikes in 2004, and I know that Tim has still been riding the Step Compo around London at times. It's highly unlikely they will have bought a new battery from Japan, so there's a life indication of nearing four years for those top grade batteries, meaning low loss over time.
