then I'm more inclined to think that they want to boost up their summer market without additional effort letting the customers have the overtrees all at once.
I will definitely profit of this chance... usually when they sell overtrees when they release a model, the lower price of the overtrees is vanished by the shipping costs and they only are useful if you buy the profipack, the T-shirt and so on in order to go over the free shipping threshold.
I bought some overtrees for the new SSW DIII, but I was tempted to buy the J1 as well, but all considered, I concluded that a weekend or profipack edition is better value. Their on-line prices are higher than those that you will find in what some shops... I imagine that it is a policy to keep the distributors and the shops alive all over the world :-)
I don't think that they will leave the WWI field as long as we buy their kits (I have some hundreds stashed, anyway... in the case of a catastrophic Eduardexit :-)).
The SSW D III is almost at WNW's level and I'm expecting their SE 5. 1/48 would be the election scale for WW1.
I advise the fellow modelers: buy some SSW overtrees and a Pheon Decals sheet, you won't be dissatisfied...
