Maybe this is blasphemy on Pinside. But, I really think we can get a lot of themes for virtual tables without all of the capital for making physical machines. I am waiting fingers crossed on a TBL, because that's a dream theme for me.
The industry overhead seems to be in the physical design. There is no shortage of ideas out there. There is no shortage of design capable people in the community. I'm super excited for Scott Danesi, but maybe one game every few years can get to market like TNA. If we like these themes, we should start working on them virtually.
I always post Insane Clown Posse, for the "Magnets... How do they work" magic magnetic multiball.
