I can kinda see it in this way... What we have now is exactly that, a tutorial. A sort of pregame to allow both legacy players and new ones to get to about the same point to make up for the fact that the previous incarnation was so bad while not giving those legacy players such a huge advantage.

Everything after level 50 is essentially where the real game begins... Unfortunately this is also where current content ends. The next few content additions will probably be geared towards raising the level cap and moving away from what FFXIV originally was. It'll probably just end up taking a year or two before there is any significant post 50 content.

People who are screaming for content NOW and are comparing it to other MMOs fail to remember that it took WoW a few years and several million concurrent subscriptions before Burning Crusade was even a thing.
