Quoted from jgentry:
I don't think the majority of pinheads are clamoring for Bon Jovi or Iron Maiden. Iron Maiden has it's followers and Bon Jovi might still be fun but neither are exactly slam dunk licenses. If either are made and the games are good I'll play them. Neither make me want to buy them though and I'm a big fan of music pins. If they are dream themes for others then that is great for them, I don't mind setting out a few releases. Not a big deal either way.
I disagree with Iron Maiden. It’s definitely a slam dunk when you get beyond North America. I think everyone will be surprised how well it would sell.
