Correct me if I'm wrong but I don't think anyone "wins" a hashwar. They just go their own separate ways, don't they?
A popular saying is that in war there are no winners. Yet, often we talk of wars as won. In theory CSW could be able to marginalize the ABC side, possibly making SV the main cryptocoin
There are huge advantages to being the clearly dominant coin, even if the other coins do not die out completely (I think it is almost certain that many coins will go on, even if small)
Still, CSW has openly talked of attacking the ABC coin to make it useless by mining empty blocks, and conceivably it could be totally abandoned in the end
