The great thing about this forum is that it connects us, dealers and makers. But I seriously doubt that a simple post like this will motivate dealers or makers to work on certain models.
If I interpret the information I read about the makers correctly (mostly from Angus' Industries Insight sub-forum) they choose the models mainly based on two factors: amount of potential buyers and complexity of the model (or rep part availability). They will always choose what ratio is best in their eyes..
So maybe we could improve future "please rep this watch" threads by trying to find plausible arguments and estimations for these two questions.
In case of this thread the buyers power could be estimated by the number of views or a poll like "Would you buy 502003? Yes / No" - the ratio might give some hints even if the number of votes ain't high.
The parts availability/build complexity is another thing - movement is there, 3777 PP dial producer should be able to make this thing but the ceramic case? When was the last time a new repped non-glossy ceramic IWC case was released? Based on these thoughts we will see a BP PP much sooner than a BP Rodeo. [EDIT: Just realized the BP PP was released some days ago, I missed that]
Just my two cents, but I think by formalising these kind of threads both sides would profit.
