Naoki Yoshida's Comment in Regard to Jump Potions/Boost Potions

[Lambdafish]

They have already stated several times other key features won't be locked to the story

You mean like entry into stormblood? Read the first post of this thread, you need to beat 3.55 part 2 to enter Raelgars Reach (or wherever the expat starts).

It would take quite a bit of rework just to accomplish an in game skip

Isn't the jump potion an ingame skip? won't it take the same amount of time? (except with one being A) free, and B) far more intuitive to player experience). As I said, the technology has already been used within the game.
