On touringplans.com I just read that the buy 4 get 7 deal is going to be announced next week. Value resorts are suppose to get a different deal. I will paste the little snippet below.
"Details are still being worked out, but weve heard from multiple, usually-reliable sources that Disneys Buy-4-Get-7 deal will return next week. The announcement may be made as early as Monday, but could be as late as Thursday. Value resorts will have a slightly different Buy-5-Get-2″ deal. Travel dates, we hear, could be October 1, 2009 through March 31, 2010. Book by December 20, 2009 (we think thatll be extended). And you must purchase Magic Your Way tickets to match the number of nights of your stay." from touringplans.com - news link
