For what I know of mass production, they make big batchs. they produce, control, pack, and then they wait the whole batch finished and ready to ship everything. They can't ship cameras one by one, it would be too expensive, they use boat and full containers.If it is built and packed, why is it not being shipped? Would not Canon want ROI as early as can?
It is even more true for brand new products launching, as they ship to the locals canon dealers in each continents. It take time, they use boats, it is long, everything cannot be synchronized. Then they wait every continent has received the first batchs of products to make the final delivery to local stores in the same time (more or less depending what they promises to the final customers)
So there is a good chance your camera is allready produced, but waiting in Asia or in your dealer's warehouse, waiting everthing is ready for final ship.
