I think you're both right, Hed Rulk and Doc; mini-busts of these characters would be great, but it would benefit Randy to stagger the releases so that consumers weren't given the simultaneous opportunity to buy a full-size or a mini-bust. You'd want to wait until the full-size has been up for a few months, orders have come in, maybe after it's been solicited in Diamond, and then show the bust (which would presumably be tweaked for a little "added value") so as to lure new customers as well as buyers of the full-size to order it, too. The Zombie mini-bust is a textbook example of this.
So, my point is ... I want a Red Hulk mini-bust.
