even the guys in the US are not happy with the rising prices of the pro and Canadians are slowing to buy NIB and they are just over the border, things will slow soon and I bet when they do they will drop the price as they can afford to because they have taking advantage of the sales.
As for the 3 tier pinballs up to 4-5 years ago they just had one type and then introduced just differences in looks but the last few years were minor changes in play but GoT was a massive difference and if it wasn't for a half decent rule set with some new originality the pro would of really boomed. But people are being more weary and Stern are pushing it to the end. But companies like Spooky, Heighway, JJP, Dutch Pinball have a single game play game with just visual differences for their LE and only Stern do the 3 tier different gameplay thing and many people are not a fan - plus on a business standpoint is a bit poor in management as they have to stock doubles of playfields instead of just one playfield and then have to have 2 different pieces of code and there is a massive development cost there - so it be smarter to have one game with same a different set of plastics, backglass and cab art for le and one playfield and one set of programming.
You wait for the topper for GB (haven't seen it) but bet it will probably be around $1k landed to us as they are getting crazy in price and for the people who are cashed up. Stern are trying to push certain modders out of the market and grabbing everything they can . greed. Yes Gary has done some good but with Jody getting his claws more and more into the business marketing and steering the business he will ruin it.
