Will there be new summons besides the initial 3 (Ifrit, Garuda, Titan)? If so, what new summons will be introduced?

Are there plans to introduce new mounts to the game?

Are Ninja, Samurai, Red Mage, or Blue Mage going to be introduced to the game with patches/expansions?

Will there be a change to the targeting system? At the moment it is difficult to toggle through enemies without having to cycle through every enemy in the area before being able to focus on the three or four currently attacking you.
