Bob brings up some very valid points. I has started to post something similar here earlier this weekend, deleted it, but I guess I'll go ahead and post it now. Not that it really matters, we're all just here making noise in the big picture of things.
Just about every major player in the plastic scale modeling industry produces a "Wild Horsey" fighter and a Bf-one-oh-thingy. (My modeling interests are in 1/72nd, understand.) In fact, Airfix recently released a new "Wild Horsey" fighter. Why? There are already a bunch of 1/72nd scale kits for that a/c by the likes of Tamiya, Hasegawa, Revell, etc. that are quite good in their own right, why bother? Well, to borrow a thought from a friend on another forum, the sales of those fighters from Tamiya, Hasegawa, Revell, etc. don't help Airfix/Hornby's bottom line one whit. Not one penny/pfenning/yen from those sales goes into Airfix's/Hornby's accounts, ergo they manufacture them along with Zeros, P-40's, and others that are the stock and trade of plastic aircraft kits.
Now, I sure don't know why Sir PJ started WNW, and I'd venture to say no one here does either except for speculation. Did he do it for fun? A labor of love? To start a new business venture, etc? A lot of what they're going to do from here on out depends entirely upon whether they want the business to thrive and grow, or they're just doing it to do it. Albatri and Fokkers are the WWI scale modeling equivalent of "Wild Horsey" fighters in terms of sales for the bottom line. They're always going to sell. Felixstowes? Really? Heck, I'm a WWI a/c fan, and I won't say I could care less, but I'm sure not running around trying to find things to sell so I can buy one, converting a spare bedroom for a display, etc.
However, I'm rather surprised they let the Fokker-built D.VII go OOP, because, as Bob pointed out about the Fokker Tripe: it has little to no rigging, and therefore can serve as a gateway drug, errrr, excuse me, gateway kit to this niche of the hobby.
When I decided back in '94 or so that I'd start buying some WWI a/c kits here and there for the day when I could build them, there wasn't much to choose from. Eduard was new on the scene, and we all know that their attention to our niche is what put them on the map. A few years ago, they've all but forgotten about WWI, in 1/72nd or 1/48th. They started to produce WWII kits to stay alive against the likes of Tamiya, Hasegawa, Revell, Roden, etc. I cannot ever see WNW producing anything but WWI a/c, and that has its limits. (FWIW, some of us pondered a few years back how long Albatros Pubs could last in terms of producing Datafiles. There are only so many images, etc. of WWI a/c, only so much research that can be had at this point. It's a finite field.)
So, like Bob said: if they want a money-maker, produce a Fokker Dr.I. It doesn't matter if Roden or someone else has done it, Roden's Tripe sales don't help WNW, but Sir PJ and the other folks at WNW know this, and LOT more to boot. (I think we all can agree that a Tripe from WNW will blow the Roden kit away, no offense Roden.)
Just my two kopecks, off of my soapbox now,
