Only if they didn't see it coming. If they know they have a certain number available, it makes sense to save them to make the $2,000 product, rather then use them up making $150 accessories. Running out of their only full frame model would be a lot more serious.
One interesting idea I saw in a Japanese comment thread was to design the GPS unit like one of the J-limited prism covers. The idea of making the unit wrap around the prism would be a very neat solution, although not every model's prism is the same size and shape, so it would probably not be very feasible. This was just a comment from a user so no indication that Ricoh is planning this. I like the idea though.
