Just to add...alot will also depend on what kind of regulation they put on the plan "IF" they do offer it. I know last year there was some talk about the way Disney did allow those who checked in on the last day of the offer to still get the 'free' ddp for the lenght of their say...and how they may not do it that way again.
Also to add...I asked our TA at AAA if we'd be able to get the free dinning offer if it was offered...and if we'd already had our reservations made (even without the ddp). She said yes...they would be able to apply it to the reservation if/when it came out.

I'm sure that will depend alot on if our stay meet the requirements (ie. lengh, day of tickets, resort room).
