I don't think anybody is going to risk kitting the big sellers in 1/32 - Fokker Dr.I, D.VII, Albatros D.V, Camel and SE5a - while the possibility of Wingnuts' moulds re-entering the market exists. The other most popular types - Nieuport and SPAD - are covered by CSM and Roden. I can't see Eduard calculating much profit from entering the 1/32 WWI market now.
However we have seen a brief period of popularity for big multi-engine WWI bombers - mostly amongst modellers who build for competitions or vanity projects, but I think the large numbers of Gotha G.I and UWD kits left languishing on retailers shelves shows this has run it's course.
I sold my WNW bombers unmade as they were just too big for my private collection, however I would probably now buy good kits of Gothas, Friedrichshavens, etc if Eduard quality kits of these types appeared in 1/48 scale
