FWIW, I agree with this sort of lineup: I don't think 10 kWh is meaningful, and I don't know if they would go with software locks on packs after the (we are assuming) small number of people upgrading the current 60. If the 75 does give about 300 Miles, a 55 would be a good other option.I expect just two choices: the base capacity (likely 55) and the optional 75 which Elon appears to have confirmed today.
