It will never happen for one simple reason - SE makes money off of those MSQ skips and they'll be loathe to ever give up that potential revenue stream. Yoshi-P might potentially consider it some day down the road, though I highly doubt it, but the executives at SE absolutely would never willingly lose out on money when the game is currently only gaining more and more interest. Why change what isn't broken, especially when people clearly like what FFXIV is offering and the one aspect that's providing an actual barrier to entry is being nullified in three months with the simplification of the ARR leveling experience? Unless SE sees actual numbers showing that FFXIV is on the decline because of it's story you're never going to see an option to skip it that won't cost you actual money.
