Retail Release Dates?

Whenever an unexpected expense such as a medical bill or new refrigerator or new transmission hits, the figures will surely follow

I would assume their are to many factors that go into it, to ever have an exact release date. The only factory that would have a production schedule would be mattel in china.

Because stores all have a different stock and inventory, new stock and ordering is based on sell through and correct inventory counts.

A new set might be ready to be ordered but its up to the warehouse for any given company to place the orders and they will only order if they need product. From there if they order product its then distributed to stores that need product. thats why some walmarts in 1 area get new sets and some dont for example.
