Russell, From what I've read the 3,000 figure comes from the run of soundtracks which the people behind TT were involved in prior to film releasing. When they presented their business model to the studios and signed contracts, that figure is a key part of it, as they pay for all those copies to the studio up front, taking on all the risk of selling or not selling on themselves. It isn't possible to go back and now change the number on a title by title basis. The other figure is 3 years, so after that time there can be either a re-issue by TT or by the parent studio. This model has been a proven success in soundtrack sales, precisely because there is no variable in the number of copies made.
