As I understand it what we are seeing is the clearance of warehouse stocks from the NZ warehouse. Wingnuts planned to do online sales themselves but someone chucked it into the 'too hard' basket and the stock was instead sold off to international model retailers.
Naturally this has spawned theories about Wingnuts reviving the business. Not happening, all of the WnW staff now work elsewhere and while the Wingnuts company still exists, there's nobody there to design or make kits. What we are seeing is the last hurrah and from here on in the Wingnut kits will largely be condemned to circulate in the ether as collector items at stupid prices.
Those who fantasise that Sir Peter Jackson will sell the tooling of the WnW kits to another manufacturer lose sight of the fact that he's not the sort of businessman who gives away valuable assets to rivals. The tooling (which is housed in China and South Korea) will go into storage, like the full sized Lancaster replicas he made for the Dambusters movie that never happened.
The Meng Fokker Dr.1s and Border Lancaster happened because Wingnuts had not completed payments to the toolmakers, and the tooling was forfeited. Wingnuts did apparently complete payments for the Handley Page O/100 and O/400 kits, which is why they have not been grabbed by another manufacturer.
So all in all the last appearance of these kits at retail prices is a bittersweet moment and a sad ending to a company that revolutionised the WW1 hobby.
