I believe the older SAAs will continue to rise, as will older premium guns, such as the Woodsmans, Pythons, etc.

I do not believe the relatively recent Colt 1911s will rise near as much, and will probably flatline and find their niche corresponding with their inherent quality. The same will be true, I think, for the current production Pythons.

I think future production quality will drive demand and price, witness the Dan Wesson 1911 line. And if CZ follows what appears to be their current business model, we could see quality rise in other models as well.
