There are dealers and there are distributors. Dealers sell directly to the general public, often from one website, whereas distributors sell wholesale to a number of different dealers. A distributor exclusive will be sold by any number of dealers which purchase from the distributor who owns the rights to the exclusive, whereas a dealer exclusive will be available only from one dealer. Distributor exclusives will probably have different prices depending on where you purchase, but a dealer exclusive has one price. As for the sprint run vs. common production bit, I think it's safe to assume that most of the dealer exclusives will be produced in numbers similar to a sprint run and on a limited basis. This may not always be the case, but for a large number of these exclusives, including the brown PM2, it's likely. I hope that clears it up some thallium.
