I don't agree with the characterization but I do think K & C is concerned about the situation you describe.
Consider it from their point of view. Let's take a hypothetical: say a collector has decided to purchase the new Arnhem pieces and then the dispatches come out and he sees that K & C is coming out in June with a 88. He may decide to say, heck with Arnhem, I'm going to buy the 88. K & C has now lost a sale. Also consider that sometimes the money the collector had saved for his June purchase may, due to an unforeseen event, have to go pay for an expensive car repair and so forth. Then the sale is lost altogether.
It's also an inventory situation. If a collector postpones his sale in the hypothetical situation, inventory builds up and you start to have overhead costs that you might not have if the dispatches policy had not changed.
Now, I'm not asking you to necessarily feel sorry for them but just to consider the other side. Unused inventory is the bane of any manufacturer, no matter in which industry the manufacturer operates.
