I'd love to see the [Haunted] Tank back in some capacity. In fact, if I was in charge of the world, there'd be a Vertigo mini-series set in the current Iraq War. J.E.B. Stuart would still be the ghost, but this time, his descendant Jeb Stuart would be a black man, and we'd see what the Confederate ghost thought about it. Well, that's my idea for a modern, serious take on the concept, and we know how DC loves modern, serious takes, right?
So, DC, you can make that check out to either 'Bill' or 'William' Reed. I'm not picky. I should also probably have some kind of credit in War That Time Forgot, come to think of it...
