Rather than ongoings… Marvel Knights will be the home for limited series by high profile creative teams that fall outside of the realm of the Marvel Universe.
As it turns out, this actually means mostly ho-hum creative teams working with charaters inside the realm of the Marvel Universe.
The first series:
Silver Surfer: Requiem by J. Michael Straczynski & Esad Ribic (late 2006 or early 2007)
The Spider (as in -Man) by Kaare Andrews (late 2006)
Fury: Peacemaker by Garth Ennis & Darick Robertson (February)
Spirit Of Vengeance (the original, Western Ghost Rider) by Garth Ennis & Clayton Crain (late 2006).
