Let’s get the Led out already.

Quoted from HookedonPinonics:

Here are my thoughts/opinions on these themes
Back to the Future - I don't see this happening. As much as I love the movies I just don't see a resurgence in this theme.
The Beastie Boys - Nope. Beastie Boys are cool but def not a strong enough act to carry a pinball machine.
The Beatles - I am not a huge Beatles fan but this of course would make the most sense to me. Not sure how expensive it would be to get a license on this though.
Fast and the Furious - Awful movies but I can see Stern doing a pin on this. Esp with a new dumb movie coming out.
The Goonies - Awesome theme but for some reason not sure if this would get much coin drop from the younger crowd. Seems more of a nostalgic idea for those in our 30's/40's
Harry Potter - Great theme and would make a great pin but would make more sense if this came out years ago when the hype/movies were there. The theme has a strong standing power though so would def make sense.
Iron Maiden - Great band and I thought this was already in the mix so it could be this.
It - Nope. Not strong enough of a theme. I'm a big King fan but I can't see this as a pin.
James Bond - Yawn. Already have them and don't care to have more.
Jaws - Awesome theme and can see this being a real cool pin. I am not a big Jaws fan but I wouldn't mind owning one for some reason.
Jurassic World - This is prob the one being revealed. Would make the most sense and like Guardians would be a good earner on route for it being current.
Led Zeppelin - Dream theme for me. Love me some Zep and would get one in a heart beat. For some reason though I don't see this happening anytime soon.
The Matrix - Another yawn. The Matrix was awesome back in 99 and would have been a cool theme back then. Not now.
Men in Black - Yawn again. Was a big MIB fan back in 97 but the sequels killed this franchise for me and I don't see this being an earner for any company.
Michael Jackson - Would be awesome but too much drama around Jacko for this to get produced.
Mission Impossible - Yeah no. Again would be cool if it came out with the first or second Cruise ones but cant see the hype on this.
Muppets - Classic theme and would be a ton of fun. Could see this happening. As of late though The Muppets have done a poor job of staying relevant. Such a great franchise just not able to keep it going.
Price is Right - Would have to be Bob Barker for me to care about. haha. Who doesn't love Price is Right.
Pulp Fiction - Great movie just don't see this happening from a major manufacturer. Would have to be like something that Dutch did with the Big Lebowski.
Super Mario Bros. - Dream theme for me but would rather want to see a Nintendo theme. This could make sense with the new Nintendo Land happening at Universal. Nintendo might get into pinball to get the hype going.
Superman - Not sure if there is a new Superman movie but I can see this being more of a comic book theme than the movie. I just don't care about Superman.
Willy Wonka and the Chocolate Factory - Would be awesome. Like others have said, JJP would make the most sense but I can't see them announcing this before getting any Pirates off the line but who knows. Would be fun!
Zelda - Another dream theme. Would take it over Mario. But again, I am not sure if a company would take the chance on a Nintendo franchise. It would have to be Nintendo reaching out and contracting a manufacture to make.
That's my two cents on this and of course my opinions don't matter. Exciting to see what it will be. I am good with all of them except for Fast and the Furious and Mission Impossible.
