Not that I know much about whats going on but... I would snap a silver up fast if ya want 1.
With the fact that their bringing in a new line of mazes next year, I wouldnt be expecting them to be making many more of the silver. They may just be using up the last of the left over shafts they still had.
I could be wrong, they might make more. But I wouldnt risk it...
