Welcome to the club!
My dealership was telling people 12 months, but 22 sounds much more realistic based on what I have read around here. But who knows? It is sort of like predicting the weather.

There is always the option of adopting an orphan if you just can't wait.
I put my reservation in at the end of May, so I'm in the same boat. On the plus side, there may be more models available when it is time to configure. I'm hoping to land a Micro Hybrid Drive model in Passion trimmings - if there such a thing existes then. Hopefully all of these little glitches will be ironed out by that time as well.
There are several smart car books on Amazon, which may help you pass the time while waiting for the car to arrive. That's what I'm doing.
Best wishes
