I could be way off on this, but I don't think I am.
I think these guys have developed an emotional attachment to their firearms.
You're way off. Seriously. I personally know at least five of the dealers who were there. Most all of the dealers in attendance have zero personal attachment to what they're selling, no matter what spiel they tell you. It's all about the bottom line (and a healthy dose of greed), worsened by dealers immediately cannibalizing each other when any deals pop up and putting the stuff for sale on their own tables for much higher prices.
