I don't think Square Enix has completely thought it through.
The class quests and storylines were already designed to end at level 30, which is where the job quests take over. Rewriting the stories to remove them sounds like way too much effort on their part for a change that isn't required.
Now what I can see them doing is removing the ability to differentiate between a class and a job later in the game. Perhaps we won't be required to level up the secondary class to 15 before we can immediately go into the job quests. Or they'll phase out the "oops I forgot to equip my job's soulstone" thing. It could be nice for newer players to be able to continue on without having to level anything else up, although I feel like that could make their experience very different from mine.
One major issue I see with my speculation is the Arcanist to Scholar/Summoner split. There's no good way to easily handle this as some form of a class/job merge. While it may be the only class split into two jobs, it's still going to cause a headache if they try to break Arcanist apart since those jobs really only split with the types of books you equip.
