Yes, expect DVC to be selling the units and not just make them available for current DVC owners to use. There has been a lot of interest in offering DVC units for sale at Disneyland and this serves as only a glimpse of the first phase of bringing the DVC to Disneyland.
Already the resort has run a promotion for Annual Passholders- there's a contest right now where Disneyland AP holders can apply for a chance to win a 3 year sample DVC contract good for up to 225 points per year to use at any DVC property but the contest rules also make it clear they are collecting passholder information for marketing purposes (I expect them to be the first to be contacted with details for buying into the DVC at the Disneyland resort) since there's a good number of AP holders who are not local to the resort that would be an ideal target group.
