It looks like Disney will be restricting resale benefits with a new restriction date of April 4, 2016 to be grandfathered.

This is from the Member Site:
You should not purchase or add on real estate interest in a Disney Vacation Club Resort in reliance upon the continued availability or renewal or extension of these offers. These offers may only be available to Members at various times and may or may not be renewed or extended. Membership Extras, such as vacation options in the Disney and Concierge Collections, certain discounts, offers, and special events are incidental benefits. These incidental benefits are subject to change or termination without notice, may require the payment of a fee and cannot be combined with any other offers or promotions. Membership Extras are also subject to availability and block–out dates may apply, including high periods of demand such as Christmas and New Year’s Day. To receive any Membership Extras, purchasers must present a valid Disney Vacation Club Membership Card along with a corresponding valid photo ID. Disney and Concierge Collections options are not available for ownership interests not purchased directly from Disney Vacation Development, Inc. after March 21, 2011, and, effective April 4, 2016, Members who do not purchase an ownership interest directly from Disney Vacation Development Inc. will not have access to Membership Extras.
