Sounds like production is going to start with the 75 kWh battery pack option only at first. I would like to discuss the possibility of M3 coming out of the gate with both options via a software lock. Why not only produce 75 kWh batteries with software locks? They have already done a software locked 60/75, so it shouldn't add significant complexity to hinder the production ramp? In the long run this would simplify production and generate additional revenue assuming enough people eventually unlocked them. I understand Tesla is super focused on the production ramp and keeping things simple at first, but they are also known for long term strategerizing. Also, this allows additional customization options for early reservation holders, while keeping production simple. Personally I would rather have a software locked 60 and spend that 5kish on other upgrades. I would probably end up unlocking the battery at a later date, but maybe not...most us of don't truly know if the base range will be sufficient or not. I would hate to forgo certain options/upgrades for the larger pack and come to find out later I would have been fine with the smaller pack 99% of the time. I apologize if this has already been discussed in detail, or confirmed/denied already.
