While it isn't official, Bleeding Cool has posted that the new writing team for Supergirl is the tandem of Michael Green and Mike Johnson. Here is that link:
And here is the brief blurb.
I understand that the writers of the yet-to-be-announced Supergirl #1 are Michael Green and Mike Johnson, best known for their Superman/Batman work.
Green produced and wrote early episodes of Smallville and is also co-writer of the Green Lantern movie, the Heroes TV show and the creator of Kings. Johnson co-wrote for Kings, as well as the Fringe comic.
Okay, I'll admit that I was holding out hope that Bryan Q. Miller would be the writer for Supergirl. And I also know that I haven't read much of the Green/Johnson team's books. But what I have read, I have enjoyed especially from a Supergirl viewpoint.
First off, they wrote the absolutely fantastic Superman/Batman #62 (cover seen above), a World's Finest team-up of Tim Drake and Kara. Here is my review of that issue for those who don't recall: http://comicboxcommentary.blogspot.com/2009/07/review-supermanbatman-62.html
It was a really great issue with Supergirl and Robin teaming up to stop a riot at Arkham. It also included one of my favorite panels from 2009, the above panel (which ranked #6 on my Top 10 Supergirl moments of 2009). In this flashback story, we see a brash and somewhat impulsive Supergirl who gets her first look at the ugly underbelly of the Batman Rogue's gallery.
But we also got Linda Lang! And a very nice friendship between Tim and Linda. Green and Johnson seemed to incorporate so much of what Sterling Gates and Jamal Igle were doing during their concurrent tenure on the main book in this issue and hopefully they will continue that tone.
That issue was really one of my favorite books of 2009. I can't believe it was that long ago.
I haven't heard Rafael Alburquerque's name attached to any other new DC book. If he is on Supergirl, I will be one happy fan!
They also had Supergirl play an important role in the Super-Bat story arc which ran a few months before the 'World's Finest' issue.
Here is a link to my review of Superman/Batman #56, the ending chapter of the arc: http://comicboxcommentary.blogspot.com/2009/03/review-supermanbatman-56.html
I loved how Supergirl basically plays the voice of reason while the JLA tries to slug it out with a Kryptonian-powered Batman. She is just a sensible hero trying to end things peacefully. Also a very nice moment.
I know it is a small sample size. Three issues guest starring Kara is not the same as piloting her title. But Green and Johnson just seemed to 'get' Supergirl in those issues. So I am optimistic to see what they have in store (assuming the rumor is right).
I hope they do an interview somewhere (like Gates did before his run) explaining what they are hoping for the character.
