I think a lot of people are just being impatient, personally. Perhaps because I was a late reserver, but I didn't expect too much - granted, I did confirm earlier this week (which was rather surprising).
The fact of the matter is that we don't know everything that is going on behind the scenes at SmartUSA. While we would like to, no one has been able to figure out for 100% certainty their shipping algorithms.
We can criticize the lack of information all we want, but attacking the reservation and delivery process is a moot point without knowing all of the nuts and bolts of it. This is a new venture in the US, and much like Canada when the 450s came out, we are getting a small percentage of what comes off of the line.
