It seems like DnA are ending their run on Marvel's Cosmic line and/or Heroes for Hire, so their schedule will be lightening up soon. They are on good terms with Marvel, DC, and the independants. What team would you like to see them writing next?
Personally, I would like to see them on the New Avengers after Bendis leaves. They wouldn't be well received writing the main Avengers comic, but the way the handle quirky, second tier characters might work great on the "other" Avengers book.
