Let's remember that sales are what drives Stern to produce a certain title. They won't build it if they don't think that they can sell it. Just because a band is popular and has sold X # of albums doesn't mean that they would make for a successful pin title.
Successful titles ("ACDC, Metallica, GNR")have every aspect working for them in their favor. Miss just one thing and you end up with a disaster (sales numbers) like (The Rolling Stones, Elvis). Very popular with music fans but popularity did not transfer over to high pin sales and therefore manufactuors took a big financial hit on them. Because of this, they will be reluctant to make another music pin for any band that is less than a "Super Star" / Rock Roalty calibur group. Therefore no Pearl Jam, No Iron Maiden, and no Queen pins anytime soon. Sorry to say this, but it's just my humble opinion. I for one would buy a "Queen" pin, love the band. I also think Iron Maiden would sell a lot overseas. But neither would sell well enough to justify the risk of producing it in the hopes that it does well. That's a shame because I think we are missing out on a lot of good titles because of this. Manufacturers are not willing to take risks anymore. They want sure things and in today's business climate, I really don't blame them. One mistake might be fatal to a company. They need to choose wisely.
