Quoted from DerGoetz:

Eric designed JJP GNR¿?
LE at minimum, possibly CE, done deal.

Quoted from drfrightner:

This post is begging for a reply... clearly you're lost in the woods on this one. Stern has some kind of program to design pinball games, and within that program is the parts available. I don't remember the last time I saw a part on a stern game that hasn't been repeated over and over again. Not to mention they reuse ENTIRE playfield designs like Batman or Beatles. Stern is not being accused of putting much original into their games these days that is just a fact. Look at Black Knight where is anything new there? Where is the effort? No one even the people who like the game are saying anything other than yes the playfield is barron.
JJP games have a screen twice the size of any Stern game. JJP includes cameras Stern does not. JJP are typically wide body clearly adds cost, Stern are not. In fact when is the last time they did a wide body anyone remember? JJP games for the most part are all powder coated, even LE Munsters wasn't powder coated most of the armor is BLACK.
JJP is doing things no one has ever seen with playfields like adding metallic flakes never saw Stern do that. But last but not least all JJP games are a one of a kind, designed from scratch with no thought to parts, or how to get them. In other words everytime they do that they must get custom parts where Stern just orders the same things as last time.
Clearly Stern makes more money off their games, because they don't put as much into them, plus they re-use designs, parts and more. There is good things about that, their games are using tried and true parts, where as JJP are using one of kind parts. Pros and cons here... but give me a break JJP games put three maybe five who knows possibly 10 times more into the games than Stern hence the higher price.
There is an old saying if you don't like the price don't buy it. I'm no longer buying Stern LE's unless they put some effort into the games to make them worth $9000.00. There isn't a single not a single Stern game that runs $9000 new that has as much into them as an LE JJP. Who can argue that point?
C'mon!
Here is the bottom line if JJP dummies down what they do like Stern, which is an option, they can't sell games for $6500.00. Its not possible.
A standard JJP has more pound for pound than ANY Stern LE by a mile. No one could argue that no one. Now you could argue that a Stern game is more fun, better this or that, but we're not talking about those aspects, just which game put more into the game itself.
Not a single stern game ever made, ever, has as much creative effort put into the game as anything JJP has ever created. Does Stern have game more fun than JJP yes they do, but they can't make a case they put more into a game than any JJP.
Why is it JJP starting putting full color screens in their machines from day one, while Stern kept producing typical dot matrix screens for years after?
There isn't a debate here... JJP puts more into their games, they're more original, more toys, wide body with big screens, simply put the real question is how can Stern charge 9k for black knight, while Wonka LE is the same price. Explain that?

Quoted from Honch:

Idk. Other than adding callouts I doubt the update would do anything about the style in which they designed the sound package.
Sound really is too integral to the play of a game for it to be something you can dismiss or overlook. I actually got rid of my Medieval madness years ago because I found the callouts(especially the trolls) to grating. Otherwise I thought the game was pretty cool.
