With the volume of new titles hitting the market this year, I think DMD era titles are going to be pushed down in value a bit here soon. This doesn't include the A-listers so much, but I see some pressure coming on the $3000-$4000 price point games when lightly routed Stern pro's are out there at $4000-$4500. Route operators are going to be dumping more lightly routed games on the market as they try to keep up with the flavor of the week titles coming out.

This is more where I am coming from...and i'm just one random guy:

I'm of the belief that TAF sells for more more because of nostalgia and status over being a supremely great game commanding $7k worth of fun. I am not saying its a crap game by any means, it just doesn't hold its own in my own measurement of dollars per hour of fun ratio. Lots of people love it, but i'm not one of them that would ever love it enough to own it at current market prices...so this is good news for me. If what you say is true about Stern Pro machines...and it appears to be looking that way, i'll have a wall full of pro's when they trend under 4k. I get more hours of fun out of GOT, IMDN, etc than I do with WH20, IJ, TAF, CFBL, etc. Doesn't mean I won't put some quarters in them on location, but I would rather invest $4k in a deeper modern game when it comes to home use.
