Did you know that Ed Brubaker is working on a new book?
No? Well, I don't, either, but it certainly seems that way. Over last two months, he got a temporary co-writer on Daredevil and a permanent co-writer on Uncanny X-Men, and now it's been announced that Brubaker's final issue of The Immortal Iron Fist will be #16.
So, what is he doing with all his new spare time? Well, both Thunderbolts and Wolverine are up for grabs later this year, a Brubaker-written Iron Man would be a nice companion to Matt Fraction's Invincible Iron Man, and Brian Michael Bendis has been on Ultimate Spider-Man for quite some time now.
Unfortunately, Newsarama's Steve Ekstrom doesn't ask why Brubaker and Fraction leave Iron Fist, so your guess is as good as mine.
