the figure my dealer told me some time ago is that they averaging 20-25/mo. factor in 75 dealers and that's 1875, on the high end of the scale. for a 12 month period it would come to 22,500 cars.
remember, all the dealers did NOT open the first of January. some are either still opening or have recently opened, like Cincy. also, realize that as the year goes along, they'll be able to deliver a few more cars than they did the first couple months.
i can imagine that they DO have 50,000 reservations just from the US. also keep in mind they have reservations from Europe as well, although their waiting period is much shorter. i really don't know at what rate the cars roll of the assembly line (i'm sure someone on here knows for SURE), but the DDE for my order says it will be 18 months from the time i placed my reservation to delivery and i believe that's pretty close to correct. i don't like it, but it's probably accurate.
for those who are impatient (ok, most of us fit that bill), the orphan list is the way to go. i myself am waiting for the one i'll order. i have some other things to do first (a bet with my wife to lose 50lbs and sell my Corolla) so the wait will be just an inconvenience.
if you're truly interested in owning one of these little jewels, be prepared to WAIT, WAIT AND WAIT some more. maybe you'll get lucky and get 'The Call' one day from your dealer saying they have an orphan for you. but until then, don't hold your breath.....
