If they were not moving the factory, I would agree with you.
If I was running the factory and we had plans to remake a pin like POTC, I would have held off on the remake and ordering of parts until after the factory move. The factory move had to been in the works at least 12 months, if not longer. This gives you plenty of time for planning.
Why order lots of replacement parts that you are going to have to move from one location to another? You want to use up your parts before the move in order to limit losses due to damaged parts or things being misplaced (lost) during the move. It would also cost additional money to move a bunch of parts that your could have just waited to order after the move. Think limiting losses while moving a factory.
I would wait until after the move to have my suppliers build me new parts.
Since these companies like to keep vaults and remakes so secret. They most likely would not sell any new replacement parts until they have released the remake. If you start selling replacement parts that were out of stock, it might signal to buyers that a remake is coming. You also wouldn't be sending out parts to customers because you are moving them from one location to anther. Maybe they have replacement parts and chose to pack them up for the move and not sell them yet. In addition, if you had all of the parts on hand to fulfill replacement orders, customers would be clamoring even louder about them remaking the pin because they have all of the parts to build more. If you do not have parts on hand, the noise from customers will be lower.
It would also be easier to let your stock of replacement parts dwindle to nothing. Then when it comes time to place orders for the remake, you include your replacement parts quantities in with the remake quantities. One order for both sets of parts.
I could come up with lots of reasons to be out of replacement parts. But at this time, the factory move makes the most sense as to why they do not have them.
Now, 9-12 months after the move if there is still no replacement parts, then I would say no remake is coming in the near future.
They also are pretty good at scheduling their new pin releases. They also would not want to remake POTC at the same time they are going to release a new pin like GNR or Toy Story. The remake of POTC would be scheduled in between new releases. Then buyers do not have to pick and chose which pin to buy.
One final word, I know this is a long shot, what if JJP took some time to work out the issues they initially had with POTC and is planning on remaking it as it was originally intended to be made. With all of the original features. This would be a way of showing customers that you can build what you originally intended without admitting to failure. If they never remake it and never correct the issues they had, then they truly did fail.
And lastly, maybe there was licensing issues that prevented them from remaking it. I know nothing about licensing, so I will leave this up to the experts.
But until the move is complete, factory is up and running, new pins being released and customers receiving the new pins, one can only wait and see (hope).
