From the previous quarter's program, the process appears to be:
1. Wait to hear from Tesla
2. Keep waiting
3. At some point you might get email asking what kind of bag you want
4. Wait some more
5. Nobody has been able to wait long enough to find out if something else happens
Like most things Tesla, you could be sorely disappointed if you try to attach a date to things. Just let it go, and most likely you will be happy one day when you get a nice surprise.
