Class Names in A Realm Reborn

[MikkoAkure]

Where is third class like pet-class which also won in player's poll?

The quote said that those are the classes that have guilds already in the game. The musketeer and arcanist guilds are both open and in Limsa Lominsa. This post Camate quoted doesn't mean that both classes will be available at 2.0 launch or that there is a missing class that won't be in 2.0.
