Marvel.com has a
Q&A with Allan Heinberg about Children's Crusade, including some mildly spoilerly comments about Doom and new preview art showing him in action. Looks pretty awesome.
Issue #8 is now scheduled for December 28th (and fingers crossed, might actually arrive this time, since it seems likely the previous delays could have been to do with setup for next year's X-Men versus Avengers event that Marvel just announced).
