Eduard are a commercial business, and as such, they will continue to do what they consider as commercially viable. Whilst I do not agree with their current marketing methods (ie presuming to know more than what the average modeller does about what the average modeller wants), their marketing must be working for them with their other era (WW2 and later) kits.
I believe that Eduard is purposefully moving towards "mainstream" aircraft types to maximise thier profits (as any business would), and not because there was a genuine hole in the WW1 kit market (c'mon, the DML triplane and SPAD XIII are actually very nice kits). We must not forget that WW1 is still a niche' market in many respects (how much aftermarket attention do we get for example?), and I predict that Eduard will fire out the Dr1 and SPAD XIII and leave WW1 alone for a while to persue their established WW2 and potential jet market base. Afterall, they basically built the WW1 market in the last 10-15 years and they likely feel like they owe the WW1 modeller nothing. And I think that's a fair stand point.
So whilst I don't like what they are doing with their marketing (and will happily argue about it), I am happy to acknowledge what we owe them.
Market wise, Roden will continue to persue their "low-tech high volume" strategy. I think there is a real opportunity for Roden to step up to the plate and really start to corner the market - all they need to do is start adding things like photo etch in their kits and they will take it (yes Roden frustrate me in that they continue to refuse to step in to the 21st century with what they include in their kits, but hey, I am picky

). Other than that, I predict that we may start seeing a small resurgence in some of the Eduard "Spin-Offs" like Gavia (ie the Albatros D.I for example). We may start seeing modified Eduard kits come out, perhaps things like a mainstream Nieuport 24/27 based on the Eduard N17 or the like (Hi-Tech persued this strategy with rather mixed results). At least that's what I hope
