Well here's something for you.

The first version of this game failed hard. This is basically a reboot. Would you seriously include a 500 hours worth of content into a game reboot knowing how bad the first version did?

This was the trial basically. Square was unsure if the game would prosper or fail, so they were cautious. No big deal honestly. 2.1 hits next month, 2.2 not to long after that, and then 2.3. The fact that the game hasn't gone down the crapper is a good sign, so expect stuff in each update. Who knows, the first real expansion may hit sooner then we think.
