Welcome.
There are many posts discussing this release circulating already. We are anticipating winter discounts in the next week or so but nobody knows. The initial release is typically Disney Visa card holders only. Then a General Public (GP) release a few days later. I would suggest subscribing to one of the already established threads as there are many posters there who will post an update as soon as anybody knows.
Last year they went through April 12th but who knows how far out they'll go with the initial release in October. Easter is April 5th in 2015 so that could affect blackout dates.
