Does Hasbro claim anywhere that the MTO model is a one-time only production run? They don't disclose the number of orders, do they? I don't feel this is like a Haslab where you kind of think this is your only opportunity.
I think they are just using this to confirm that if they needed 5,000 orders to go into production, getting 7,000 preorders covers that and they can possibly make 10,000 and not lose money even if they have excess and it takes awhile to sell. And if they get 1,000 orders, they can always say "sorry, didn't get enough interest, your preorder is cancelled".
