With a boatload of first appearances and all of them on this cover, JSC's variant is going to be a must have, and we've got the virgin variant of it, limited to 3000 copies.
Blue labels will ship in May. I expect SS books around May as well, but this is purely speculation as the signing is out of my hands. I will ship as soon as I have them in hand.
