Quoted from leonml:

Yes but oversaturation of a good thing will make for copies of copies of copies of ideas for money sake, decreasing value and loss of interest. Eventually something will be deemed collectable or valuable perhaps and the rest just novelty. Who knows. The More pinball machines made, the cheaper many games will get. Already seeing it with newer releases and prices In the tank so some can own the latest and greatest. Sooner or later something will give. There's only so much money and so many buyers, but a never-ending supply of new games and remakes.

Quoted from leonml:

Yes and no. stern for instance isn't even trying to bring pinball into this century. They aren't even matching what Bally Williams best was in their heyday. Pinball is repeating and cloning old ideas for the most part, for money. There's already kickback for this. I could tell you several new ideas that the so called experts making these should be already doing.
1. Why not get rid of flat glass pf covers for ones that are formed to house ramps and such that come up above where the glass would typically be? Imagine the insane ramps and loop d loops and toys.
2. How about backbox with a flawless seamless game play that actually had something to do with the game instead of a glorified old school original Nintendo look and feel. Why not an actual pinball ball that carries gameplay into a vertical playfield? In most its just a pretty video display like watching tv, more for the onlooker.
3. They could add to the 3 dimensional feel of idea 1. and make more room deepening the pf inside the cabinet with room for more integrated and seamless play with multi levels. this is where wide bodies could've really better utilized the area of play and advanced the gameplay.
4. Why not evolve flat pf altogether, with a more dimensional one, not like orbit, but have dips and bumps that carry the ball in cool crazy ways, and with a good design you could still make for controllable gameplay where there's less ability to know where the ball will go for sure and make you adjust gameplay at a moment's notice to a multitude of possibilities that lead to good tough high scoring shots.
5. Playfields made of painted cleared wood should be yesteryear. It's a recipe for disaster with varying expansion and contraction ratios of paint vs wood vs clear coat vs whatever.
6. Steel ball bearings that rust? Come on. How about ceramic, or ceramic coated steal for magnet games. I'll pay more to never have to worry about the problem.
7. With mirrors and light you can add dimension and illusions or trickery of the senses to make you think your seeing things.
They don't even utilize mechanical toys to their fullest. Simplest of movements and action. Should have toys that actual defend against your moves. A hulk that swings his arms and fists when the ball is near. Would look better then just magnets moving the ball too, which is great for magician themes and spirit themes, perhaps some superhero as well.
