As most of you are aware, the biggest hurdle for operators running pins these days can be summed up as "too little return on investment." Nowadays, IF (that's critical) the pin is a winner, the operator could theoretically buy new, run for a year, and recoup most of the purchase price. Of course if the games a dog, they're going to be stuck with it. But this is all a gamble, which a struggling business is unlikely to want to take a risk on.
I think initial purchase cost (talking about "Pro" models, at least), especially compared to the price of many/most of the newer videos, is not the major deterrent. If the games were making good money, operators would shell out the money for them. But when you can route a 15-20 year old Williams or Gottlieb System 3 (that paid for itself long ago), that will make within $10/week what the brand new one does, it doesn't make sense to buy the new games. If the new games were grossing $100/week more (especially as most pins around here are lucky to pull in $20/week) then the ops would be taking a closer look.
I think companies like Stern and JJP are going in the right direction switching to LED only. That will help cut down on maintenance, and saves the op time and money. Also, from my experience, the SAM system from Stern is rock solid, so aside from PF issues, the games stay running. I will admit though, the last couple new Sterns we bought have had issues directly related to the cost reductions (thinner ramps breaking quicker, more broken wires under PF, things like that), but nothing catastrophic. Obviously flashy stuff like LEDs and LCD displays and the like are good eye candy, so those sorts of improvements are going in the right direction.
What I, personally would like to see (whether or not it would help is certainly debatable) is more integration with both social media and smart phones. For example, in some locations, we're seeing a large increase in the number of people using the TouchTunes app on their phones, for controlling the jukebox. You can simply whip out your phone, fire up the app, select your songs, and you pay for them through the app. The customer doesn't hardly have to lift a finger, and if they play something like "Barbie Girl," then no one knows who to blame!
I'd like to see where you fire up your pinball app on the phone, check into the location, and the app shows you the games that are there (maybe even things like high score and replay score?). Select a table on the phone, and how many credits you'd like to play, and pay through the app. Completely cashless location pinball.
The rest of my ideas here could be done through other means (maybe a card like some racing games use, or your own USB stick that plugs into the front of the machine), but I'm going to keep using the context of app. I think it'd be sweet to have the game compile your stats for you. If you keep playing, say Star Trek, and the app (or USB or whatever) kept track of things like your scores, number of ramps/combos/etc, what modes you've started or completed, average ball time, etc. etc. I think a lot of semi-casual -> semi-serious player would play more seeing this sort of information, as it gives them goals to strive for. Also, with the machine/app keeping tracks of stats like this in a profile for you, it would allow for an easy implementation of virtual leagues and tournaments. Maybe Joe's bar runs an in-hose tournament over the course of a week, come in at your leisure, play as many games as you'd like, and the app tracks scores, winner gets a trophy, T-shirt, money whatever...
In addition, to payments, the app would do other things like announce on your Facebook or Twitter things like the location check-in, and then like those crappy Facebook games, show when you set a high score, or even just a replay. Although it might be spammy, seeing over and over how "Dan earned a free game on Metallica pinball at XYZ bar" or "Bill is the new Grand Champion of the Star Trek at ABC Diner" generates buzz and interest, which in turn leads to more play.
What I would envision is one server, per location, that's online and interfaces with the app server. The machines could either be hardwired to it, or connect up with Bluetooth. All the machine has to do is report its individual audits to the server, to assign to the registered player, and accept a signal that put a credit on the machine.
I would be surprised if a lot of this stuff ISN'T already in the works, but if its not and someone influential is reading this, remember to send me a check
