Ok, I have been following this thread and considering all the speculation, wishful thinking and negative prognostications that have been bandied about in an attempt to answer the question in the subject of this thread.
I respectfully submit that is the wrong question to be answered. We may see repops of the molds at some point, Decals might get re-printed or the AM folks may make new ones. But that total package from box to packing, to sprues, to decals, to PE and extraordinarily documented instructions will not be reproduced as a package for these models again. Any future use of these molds will be based on the primary tenet of making a profit. That may serve to get more of these incredible sprues in our itching hands, the engine sprues would be a real money maker at this point. Unfortunately we have seen the last of the "whole package" kits that we have come to love produced. So the real question concerning WnW kits is not how many THEY have left, but how many do YOU have left? Stocks of WnW kits on hand will dry up as quickly as they are made available. There will always be a few turn up at outrageous prices as their owners die off or simply decide they need some cash. But as far as the magically complete kit packages that WnW produced, Unless you are rich or lucky, you have what you have, so savor them as you would an irreplaceable bottle of fine wine. You aren't going to see these magnificent kits in all their glory again.
I do not mean to sound negative because there are some very positive signs that the industry is picking up on the WnW example and producing kits of high accuracy and detail with state of the art instructions. Gaspatch, CSM and Aviattic among others. WnW kits may no longer be generally available, but the experience of building an exquisite model from an extraordinary kit is a legacy WnW has left us all and in that respect WnW will always be with us.
