The initial key piece of information is the Build Week. Once you have a build week then you know your car will be built and can figure out approximately when it will get shipped and therefore when you ultimately will take delivery. There is lots of info on the whole production/shipping/tracking process -- just do a search.
Dealers have a monthly allotment for X1's so the number of slots open and when can vary dealer by dealer.
Mine just went into production today!
