What I take from this is that, as a forum, we are not representative of the wider modelling community.
Lots of us bought at least one Nieuport kit, but it seems it was nowhere near enough for CSM to make a reasonable profit. So the wider modelling community didn't buy it in large enough numbers.
It's tricky, because we never knew the volume of kits WNW sold. Is there a possibility that the WWI 1/32 market is not as large as we think it is? Are CSM getting the pricing correct - a few modellers have told me the price is just a bit too high, especially with Roden kits available for around a third of the CSM Nieuport price?
Maybe CSM are making the right move by working on previously unreleased subjects, with Roden - via pricing - and WNW - via quality - having saturated the market for the types they've made.
I, for one, are far more likely to buy a French two seater & new British type than a Nieuport. I have 4 Roden's, 2 Special Hobby's & an Academy - seven, or eight including the CSM XVII Late. Whereas I have zero French 2 seaters (besides the Salmson), so I'll get at least one, several if it's a Caudron G.4 or Breguet XIV.
