If you had just placed your order, it's a possibility. If you already had your pre-order in for some time, then it's likely that it will be shipping soon. As far as the emails go, there are a few messages you will receive with different subjects throughout the process. The first one states "Your order no. 557-NISSO-00000 has been received", which is an order confirmation. The second "NIS America, Inc.: Sales Order #NISSO-00000", will be a payment receipt notification just before the item ships. Finally (you may or may not receive a shipment notification email prior to this one containing tracking info), "Your order no. 557-NISSO-00000 has been fulfilled", when the item actually ships.
I do hope they are shipping it soon. The sooner I learn about the bonus item, the sooner I can place my order. Regardless of if the info comes from NISA or from a fellow fan, I'm eager to see what they have coming with this movie. I thought the onsen towel was a great idea, and, although I didn't go for it, the bandanna was interesting to see. So I'm hoping there will be something else unique that comes with the movie.
