Buy, or don't buy, that is up to each and everyone (and their wallet) to decide. Most of us has to make a choice based on what we want the most and what we can afford.
I have to say I find some of these discussions rather strange. How much money do you think WnWs are making and how much do you think they have spent so far releasing newly tooled kits? With all the costs involved in bringing a new product onto the market I suspect this balance is rather tilted towards the red. Profit margins in the hobby industry are not that high, and as a major producer, you would have to sell thousands of kits from one tool. Add to that, WnWs were practically giving them away during the first years, well...
Of course WnW has to find ways to recoup this cost – they have rightly identified that the Albatros and the Fokker DVIIs are major hits, and they intend to make enough money on them so that they can sustain and develop other types, that perhaps will not sell like hot cake. Or would we rather they did not develop, say a B.E 2 or the Taube for that matter, which I suspect will not be quite as popular? Like everyone else they need to pay their staffs wages – just be happy they're not only producing "for sure blockbusters"!
Now, on with some modeling, and by the way a Sopwith Dolphin would be very nice!
