I don't believe Disney is too worried about resale at this point. They know they can sell enough BLT directly to meet their financial goals. After the sale, they have the maintenance fees covered for the next 40-50 years, regardless if that contract is resold 100 times. Yes, a few people will default on these contracts which means Disney can recoup those points (along with a few years worth of direct money and interest) and sell them as "new", or they can have them re-sold by Fidelity, thus covering MF's.
Once the shine and excitement and "newness" of BLT (or Aulani) wears off on a public hungry for the next best thing and a consumer that is unable to be satisfied until the next new toy is available, Disney will have most of their points sold directly for these resorts. Then.... on to Grand Floridian, Disney's version of the Ipad2, Droid 4G, or Tickle Me Elmo... Black Friday is an everyday occurrence for this company. They wrote the book on sales and promotion.
