I think that caution will be largely gone in 10 years. Hence my belief that the resale value will be better-than-ICE for a couple of years, worse-than-ICE for several years, and then better-than-ICE again around 10 years.
On the other hand, while a used EV could be revived by newer/cheaper/denser battery technology, that same benefit is what will undercut the residual value. Why? Quite simply, a NEW car will also benefit from the same technological improvements PLUS advances in the overall design. If the most expensive part of the car get cheaper, the WHOLE CAR gets cheaper. Imagine a 2nd generation MS with a starting price halved and with features and enhancements we can't even imagine yet... Upgrading a 5-10 year old car's battery would definitely reinvigorate that car's usefulness but replacement cost (for the new version) is going to be chasing that value down pretty hard.
NOT an equivalent product-- to be sure-- but would you replace the battery on your drill or laptop to get another 10 years out of it? Or does it make more sense to just get a new one with improved performance and charging capacity? Every drill I've owned was replaced because the battery improvements and prices dictated that getting a new drill with a new battery was the better deal. The drills themselves always worked fine if I had a way to get power to them.
As someone who typically drives a car into the ground (both our cars are over 10 years old) this kind of depreciation curve doesn't bother me-- but for someone concerned about depreciation and/or who bores quickly with their cars, consider this. Once the initial supply constraints are removed... no one really knows what will happen and the faster/cheaper batteries become, the steeper I think the depreciation curve will be.
