Three are know so far based on the box art images.Zatanna Zatara
Swamp Thing
Robin
They did process of elimination at this thread based on Matt Hyra said, so we know the #4 is Green Arrow
And the only list that had the first three had Supergirl and Animal Man on it. So one of those is #5.
That only leaves #6 to figure out before the photos reach the web.
I'm putting my money on Blue Beetle or a Teen Titan (probably Raven for the extra female card).
