This reminds me of how they handled the free 5.0 and 3.0 trainers. If it follows the pattern we may been in for a lot more color ways and quick markdowns on select colors.
Got mine today too. I did notice when I clicked on my size 11 it just said "add to cart". When I clicked on size 9 it said "get first dibs . . ." And it gave a date can't remember when, but you can still and to cart.
