Guardians of the Galaxy would be an insta-buy for me. A DC or Marvel universe type of pin could work, but I'd worry about the whole package being cohesive enough to be at least good.
HP would be a huge hit, and probably a buy for me even though I'm not a big fan of the HP franchise. So much to work with... Potential to be absolutely EPIC.
Doubt I would buy Toy Story, but a new POTC would interest me. No Bond, BTTF or music themes please.
Looking to seeing what's next no matter!
