Holding back this kind of product shipment will only harm company sales in the short and long run. The price for the watch will be the same now or next year, were not paying higher prices for anything. Why would we rush and buy a product that will not arrive until about 2 months later? What you say does not apply to electronic devices sold from apple. This isnt food or something that we need to survive so holding back shipments of this kind of product does nothing but hurt their own sales.
Scarcity marketing works best with luxury goods. Things you don't need. The Apple watch is one of those...
My last reply to this subject... You know, I can see your point of view, I can see how it seems the logical answer. Using scarcity as a marketing tool is not intuitive. You might call it a paradox.
