For us, "retired" means sending off dies to be recycled. They're melted down five years after the end of a production model. We don't hold on to them for any purpose other than to create service parts for a mandated period of time. If we didn't need to hold them for five years, they'd be gone as soon as possible as floor space is expensive real estate in a factory and dies are massive, heavy and always in the way when not in use. Hasbro may warehouse the fixtures for some sense of nostalgia but I suspect they won't keep the entire lot. And I also think Hasbro will be much for careful with this set than those of the past. Haven't seen the market flooded with KO sail barges.
