I hear people say they want a lot more adult themed pin, but Gary Stern said during CAX that Stern will not be doing those type of themes as the market they are targeting has shifted from bar type locations to more of a home market.
So as much as most of us would love to see that, unless some other company makes one, it seems unlikely Gary will produce an adult themed pin.
On the topic of Stern making a Hot Wheels pin- that would be something I could see Steve Ritchie doing. I think he would take a more edgy approach as he doesn't do cute. Twisty- turn style ramps with flow, really blends with pinball, so I could see this being a good theme.
