My guess is they have enough demand that the price increase will cover any pre-order dropouts and they'll still make a ton of money. Even with the increase in material cost. Personally, it's finally over my price point based on what you actually get with a Stern. I've had about 17 Sterns in the past. We have a brand new Mandalorian premium but I just could not justify it for $8,500.
Side note, I told my distributor on 100% in on a Cactus Canyon now! Well, as long as there's not a huge price increase with Chicago. LOL
