FYI, the MYW plan was announced early Dec. '04 - I remember because I switched over my pkg. on Jan 2, '05.
DVC holds their annual info meetings late Nov./early Dec...at that time any proposed changes/percs/discounts (including tix, etc.) are usually announced. Since it's been indicated that some sort of Dining Option will be offered to DVC members, I'm anticipating/hoping for an announcement @ that time.
Just a guess, but the assumption is that the dining option will be tied into the purchase of MYW tix - so pricing will need to be established @ the announcement.
