honestly I dont' think we are going to see anything big like we saw with the consolidation of arr quests,. Besides Yoshi P stated in an interview a few months ago the MSQ is central to the game and the FF series and is going to retain it to keep it in line with the FF series which is about the story first . Honestly from 2.0 to 2.5 felt a lot shorter and such especially with the introduction of flying as soon as you complete ARR. I do think they can remove alot of the aether points for flying in HW and StB and probably just retain the ones associated in MSQ or something because honestly the zones and its real drag on that part.
