Impossible to say, only that for the most part, Will plans to eventually mass produce all the prototyped designs that he feels are working well and get a sufficiently-large fan reaction that makes it clear there's interest in them. Even then, what isn't produced in one wave of accessories could always make the next mold. Balancing a production mold is a very, very thoughtful process, and no everything can fit or is appropriate for a given mold.
All in all, if there's something you'd like to see, your best bet is to post in the appropriate Tales from the Garage thread. Will loves well-thought and written feedback, especially when it comes to designs that are still in development!
