Congrats! I see you are in the Seattle area... Mine went into production on May 3rd and I took delivery May 25th... so about 3 weeks... Hopefully you will get yours as timely... those 3 weeks were the longest I've ever felt 3 weeks go by though.
I kept a record of the timeline posted in a thread you can see here.

I was told it would arrive in early June but got it a week earlier than they said, so it was quite a great suprise to get it before Memorial Day weekend for sure!
