New Expansion question

[Akizuki]

To answer this question:

Yoshida: We’re planning on doing a major update every three months once the game has been released, and continuously adding large-scale content. Ongoing support for the game will be included in the monthly subscription.
We’ve already begun work on the first update that is currently called patch 2.1 and will introduce a large-scale housing system, as well as “The Wolves’ Den” — the first ever PvP content in the series. Furthermore, the update will include new dungeons, a new daily quest system, new Primal battles, extensions to the main story, and loads of other new content to enjoy.
There will be a significant update every three months, so everyone will be able to continue enjoying the game for a very long time! Of course we also have long-term plans to release full expansion packs, so watch out for future updates on those, too.

Keep in mind - All of these "expansions" will be included under the subscription. Meaning they will be coming via patches, this includes everything listed above + future Class/Jobs.
