Mike,
I doubt seriously that Colt's 1911's are going to jump in price/value. There are way too many clones (bad and excellent) out there. The Python on the other hand is a once in a lifetime firearm and should be cherished until passed on or sold for that one last fling before you die!!! There simply aren't any clones (not sure they could be made) of the snake! It's a great firearm even though it gets a bad rap for reliability. Keep it clean and oiled and there isn't another revolver made that can touch it.
