All the design work has been done, so no expense necessary there.
Keep the price "sensible" and they'd sell like hot cakes!
The last sentence is the problem. The price won't be sensible and won't sell like hot cakes. Besides, it isn't up to modern standards. When in sale it was made to order.
In the age of high ISO the speed of F:4 isn't really needed in such a lens, and most won't find that it is worth it. It weight and cost twice as much as a 600/5.6 - and there already is the 560/5.6......
