I can see possibly paying a premium for a game if you can get a game early and avoid the long wait but PF LE's will likely have even a longer wait than the SE's. Interest will wane over time as other new machines are introduced and released. By the time PF ships it may be competing against the next KME Stern game and the next JJP game among others. Interest in the title will likely never be higher than it is right now which is why some sellers are trying to take advantage.

It's just in bad form and clogs up the Pinside forum. I could put up ads for each of my games for $2500 over the going rate hoping for someone desperate enough but I'm not going to do it even though id be willing to sell them. If someone wants to pay $2500 over it would make sense for the buyer to put up a WTB ad stating what they are willing to pay and then someone can contact them directly.
