Aquaman should be free with the purchase of 6 previous Justice League members.
Also...like the gofundme idea, I wonder if we could pre-order certain characters like some of the action figure companies do.
Like they could show a rendering and then we could see if it got enough orders to proceed. I know there's still a cost for the design though so not sure how that would work. Might be a way to get Kid Flash, Speedy, Aqualad, Raven, Cyborg, and Beast Boy.
