I don't know if you (spoonmugen) ever look at the shoes tag, but it has the production date which is usually 6 months earlier. Before that date they even have to finalize everything with the factory which is about another 1 1/2. They have to also pick/ design the colorway etc so maybe 3-4 months?
So thats almost a year before the actual release date.
