Two years ago, George Perez said this:
I've never drawn an issue of Legion of Superheroes. I'd say that's a wrong that has to be righted.
As mentioned last month at Wonder Con, it looks like he'll get his chance to right that wrong - with Geoff Johns writing it.
How about this dropped in the middle of Rich Johnston's "Lying in the Gutters" this week? (Emphasis on the last sentence is mine.)
I’m told Grant Morrison turned in the [Final Crisis] issue one script back in November. However, it was not exactly what has been previously discussed and didn’t bounce off from the end of “Countdown" as intended. It also goes off on what can only be described as Morrisonian tangents. You know, what readers call “the good bits."
So Dan DiDio flew to Scotland after Thanksgiving to discuss possibilities further. I understand the script is unchanged, but it was from those discussions that the 50 cent “DC Universe" #0, shipping the week after Free Comic Book Day, emerged. Co-written with Geoff Johns, it will keep any "Countdown" continuity issues out of the “Final Crisis" series and prepare the way... very much the John The Baptist of comic books.
Geoff Johns is also writing a Final Crisis-spinoff "Legion" mini series drawn by George Perez that will slot into all of this very nicely.
