Jeph Loeb's gonna be writing Ultimates Vol.3 for Marvel, as well as a Spidey project later on down the road with J. Scott Campbell. Hes done Superman/Batman and Supergirl for DC.This show reminds me not so much of RS, but more of an Indie book done by Brian Wood (now on DMZ, a great book, check it out) called Demo, about people getting powers. A great book out in trade now.
My bad on the artist question. I haven't looked at them yet, so I assumed Sale's work on the show was on the web comics.
