All the recent rumors have ended up being true...

Avengers
Metallica
Star Trek
Mustang
Walking Dead

Those were all strong pinside rumors. Some of them I literally bet money against (and lost!) so at this point I'm inclined to believe the titles being kicked around are accurate. We just don't necessarily know their order.

In the Trudeau interview, he mentioned that whatever theme he is working on is very clear in direction. Not like Mustang where they had to create a whole game concept. So I would think likely not a music pin since those are pretty much wide open books.

So a movie or tv show.

wow, there is money right there.

Announced in January, delivered 4-6 weeks later like normal.

Movie themes traditionally come 6 months or more after the movie, so that pin would not be coming now.

The WWE Wrestlemania makes more sense, and would be rolling out of the factory during the wrestlemania window.

I'm taking it you are just guessing, that the actual game may not have that at all? Would be a good idea to use a kickout hole as a "pin" attempt. Ball falls in there early, it gets popped out immediately, but as the "match" goes on, it will get closer to a 3 count and finally a pin for the win.

Would be a unique pinball experience.
