Current line up Rolexes expected to be "desireable" vintages?

[cruvon]

Hi, if you were to place your bets on current line Rolexes being "desireable" or "rare" vintages in say 15-20 years time which ones would you say would be the top contenders?
I would say any watch that is a current vintage is the best bet and in the new line up the Yachtmaster 2 and the previous model SD. The current model DSSD too could be a contender if was replaced with a thinner model if had falling sales.
The thing that could go against the current lineups however is mass production. They might never be as rare as the models that were sold back in the 60-70's which were not that much in abundant supply as now ina globalised economy.
What are your thoughts and which ones would you pick?

NB: I hope I haven't been asking too many questions:).
