Update #2: as a reader mentioned in the comments section, B&H is accepting orders, not pre-orders.
Update #1: I just talked to a rep @ B&H - there was no M9 waiting list prior to today, current orders will be handled on a first-come, first-served bases. No word on when and how many M9 cameras they will be getting.
B&H just started taking orders for the Leica M9 (before the M9 was listed as coming soon). I am not sure if B&H had an existing M9 waiting list, since you could not pre-order those items before. B&H is very conservative with their order business - with other brands, they don't list items for order unless they will have them in stock in few days (see Nikon for example). Maybe they will be getting a large M9 shipment in the next few days and this is why they listed it as "accepting 0rder". I will try to find out more.
