Has anyone who has ordered gotten any information on the pricing of Model X service plans? One would assume the pricing would be similar to Model S, but will replacement of the bioweapon defense mode HEPA filter be included in annual service? I wonder how much it would cost to replace that filter without a service plan. I'm leaning towards ordering the premium upgrades package, but I am sort of wondering if replacing the filter is going to be on the order of an additional $500 per year?
