Australian site Mr Toys has a page up for the upcoming 6873 Spider-man’s™ Doc Oc™ Ambush. It includes Spider-Man, Doc Ock, and Iron Fist minifigures, which were revealed already in the back of the Marvel set instruction booklets.
The box says Ultimate Spiderman, so it’s based on that rather than a movie tie-in. It’s listed at 69.99 AUS, so I’d expect $40-50. It’s slated for an August release.
