Well, this isn't the happiest of news stories. WizKids has announced that they're having to cancel their Superior Foes of Spider-Man pre-release events (you know, like how we just had that Carnage preview the other day?). The reason for the cancellation is because of a train wreck. As in, a literal train wreck.
While the pre-release events aren't going to be held, WizKids does have enough product for those stores that pre-ordered the actual line. So the launch of the set will still go as planned. It's just the pre-release events that won't be held.
