They have it on record. Their priorities are:
- Battle/Armory system changes.
- Getting the game tweaked and cleaned up into a suitable state for pay-to-play.
- Then start worrying about PS3 release, Ishgard, extra classes & jobs and expansion packs.
They have deliberately avoided putting a time frame on any of these so as to avoid getting stuck in an "epic phail" scenario.

One thing at a time.
