I am planning on getting the 40kWh pack (though the performance 85kWh version is mighty tempting!). With battery tech advancing though, in 3-5 years we could see a 120kWh pack for example. Would it be possible to upgrade the battery? Though it seems like it might not be cost effective to "dispose" of a 40kWh (possibly $20k) battery.
