It'll most likely be the original overpriced cost before any adjustments according to the 2.1 patch notes, unless they've changed their mind. They could justify keeping the high costs as "fairness" for FCs that grinded all that gil during those 3 months after the patch, which would be fine I guess. They have gone back on previous patch note statements before though, like increasing the Echo in Coil further than 15%, so who knows. It is a big grind and gil sink and they seem fine with not adjusting those a lot.
