Many thanks to all who were willing to share data. With this additional evidence, it does appear to be true that US reservations started at 10,000. User
@michael95453 indicates the most recent order date, with a 28,3xx reservation number. I'm going to assume there's nothing unusual in the reservation numbering scheme other than the initial 10,000 base, and say that as of last week there have been around 18,350 pre-orders placed in the US.
Do any of the Canadian pre-order holders have a reservation number? I'm not sure if that 18,350 estimate is US-only, or all North America region pre-orders - so maybe a forum member with a reservation from Canada can help us answer that.
My goal with this thread was to try to make a reasonable guess about how many US pre-orders are likely to be active by this fall, so I can get a reasonable level of confidence that the $7500 US EV tax "credit" will still be available. With Leaf sales up by 150%, it's going to be pretty close for a lot of us, especially any of us who ordered an AWD. Most recent Nissan sales data shows that we are only about 40,000 EV's away from hitting the sales volume limiter on the full $7500 credit.
I'll input everyone's data into a simple model in Excel and see what it looks like. I don't know how to account for direct allocations to the US Nissan dealer network, but I'll do some research (maybe call some dealers) to see if I can factor that projection into the model as well.
