Interview where Yoshida says they know a
Scout Class (read Thief) is missing. (Also mentions Ninjas/Samurais as wanted,
nothing about putting in game)
Found Here
A translated interview found on these forums from when 1.x was still running.
It specifically mentions "just a few of the random ideas (or delusions) that Yoshida was kicking around in his head, none of which are finalized concepts." However, confirmed
Arcanist for 2.0 release. (Mentions they were thinking about branching Dark Knight off of Gladiator and bringing Musketeer into game with dual pistols,
neither confirmed or set in stone.)

Interview post launch where
Ninja is confirmed, however with no date estimate.

There are plenty of other interviews mentioning there will be new jobs/classes, no specifics or timelines.
However, what I CAN'T find is an
OFFICIAL interview or comment by Yoshi that is not 'just an idea' saying that they will in fact be bringing Musketeer into the game.
I have seen plenty of people arguing because there was a Musketeer's Guild in 1.x (from Tanaka, not Yoshi) and the fact that there are NPCs currently 'firing pistols' in the practicing area for the Marauders' guild. They've data mined and found graphics that like the guild crest that existed in 1.x in 2.0, blah blah blah.
Obviously nobody can say what will and won't be in the game, but I like to go by interviews and official statements. If you have one, please link it so I can check it out as I try to stay up to date on this.
The ONLY other thing I've seen that's not quite official, but mentioned by Yoshi in interviews is that he personally would like to see Red Mage brought to ARR.

In regards to the original poster, yes we're getting a scout class (perhaps Thief class, Ninja job? who knows). To the musketeer lovers, please toss a link to an interview! I am interested in reading it.
