I've got it on good word that old 90s will not be upgradeable. The 100 requires changes to the car that have not gone into production yet.This has been posted in another thread already but perhaps gives more credence to recent 90 kwh batteries potentially being software upgradable to 100 kwh (in addition to the increased power output from recent P90D Model X vs "older" P90D Model S)
