I noticed something else in addition to the 75D being added to the Design Studio today (there are lots of other threads on this topic so I won't go into it here). For the charger it says the high amp version can be 'enabled after delivery'. Does that mean it is like the 75 kWh battery... the larger amp hardware is installed but is limited to 48 amps by software and can be upgraded over the air later??? Or, do you think that means the hardware can be retrofitted at a Service Center later on? My 70D (which is really a 75D) is on order. I was going to get a 60 amp circuit installed in my home for the HPWC but now I'm considering going up to 100 amps in case I feel like upgrading my car over the air later.
