I have to wonder if bikes like the Trek Madone, the Colnago C40, Kestrel Talon, and others that have made significant presence along the modern road bike timeline will someday be as collectible as the Peugeot PX-10, Masi Gran Criterium, Eddie Merckx, Legnano, and the like.
This brings up the question of "what makes a bicycle collectible?" I'll be honest; I'm nowhere nearly as knowledgeable on this subject as my mentors on the CL List, so all I can do is surmise and then solicit your input to help answer this question.
