AppleInsider also said that DHL is currently strained on its international shipment routes due to similar demand by Apple for space aboard its aircraft. The squeeze seems to suggest that Apple will stock its stores so that customers can pick up the iPad 3 shortly, perhaps even immediately, after it is announced. If the demand is as strong as it sounds like it will be, we can expect to be waiting in some pretty long lines for this device.
