They could build the slightly-lessened version they planned to do anyways just by shaking the change out of the seats on CoP. Alas, it wouldn't move merch or bump LL sales. And that's how we decide things now.
Back on topic, the AC plot has been earmarked - so to speak - for a larger expansion. An expansion that isn't funded yet. They were caught flat-footed with their HoP plans and are historically bad at adapting. Pressure seems to be having a tiny bit of effect, which is more than the typical zero. Still think this boots MV - which was going to be leaving within the next few years anyways under a few different plans - while AC soldiers on without another real expansion funded.
