Sounds like KISS is pretty much a cert. Not my type of music but I guess they do have a fan base. Would far rather see Aerosmith as a title. Iron Maiden might prove popular in places like South America where sales are normally less but are quite a polarising band in the UK (but then I would have thought the same of Metallica) - do think their artwork would look good on a pin though. Maybe one day we'll see a Motorhead pin

Surely the Fast & Furious is too close in theme to Mustang and I'm pretty sure that one bombed all across Europe. I know it was a film but was it actually any good? I always assumed it was a throw away film rather than one that had a hard core fan base but I'd be prepared to admit I'm wrong on that one.

Personally I would love a Game of Throne pin but I suspect the demographics of fans is similar to those of the Walking Dead. The Hobbit would also have a large cross section of the same potential buyers, so is there enough cash left to go around for all three themes at the same time?

My money would be on a music themes coming out on a regular basis to hit that middle aged man demographic until they run out of classic rock bands to use.
