We knew that it was in the offing before the announcement of his Superman Unchained run. But it never went away, it was meant to happen after his Superman run. Which is to conclude soon. (Although… it is interesting that Geoff Johns and John Romita Jr will join Superman rather than take over the better selling Unchained. Interesting decision…)
And… the cover of Future's End #1 seems to have a certain familiar figure, previously dropped out of the New 52, back, front and centre.
So… how long do we have to wait?
