NCsoft's resistance in selling, well, anything is why we went to Disney first, in fact - the consequences of refusal {and I don't mean in any kind of illegal sense} would be too obviously severe even for NCsoft's execs to ignore, especially PR and investor-wise.
And like it's already been mentioned, it looks like #savecoh managed to erode at least some of the muleheadedness, now that they're backtracking with "nothing's been decided".
