Excellent find, Scott! Very cool stuff. Looks to be an outstanding kit. Thanks for posting. With regard to the D.IV, that one may be released at a later date, but even if it isn't, I think we both have the Koster kit and we can easily use those wings and struts to do a simple conversion. The Koster resin wings are pretty nice and won't look too out of place on the Eduard fuselage.
Cheers,
Bud
