It is impossible to predict a precise date as to when a certain model year or equipment configuration will be available due to Tesla's policy of matching up orders with production.
Sometimes you will order a certain configuration, and Tesla will find an exact match out or stock or in transit. Other times you will need to wait till it comes down the line.
In addition, Tesla has a policy of continous improvement. You will never know in advance, for certain, that any specific configuration will come with your order.
Best way, if you absolutely must have next years Model date, is to tell your delivery specialist that you are willing to wait for that configuration to be available before matching.
