Solo Play

I was wondering what Kind of solo features will be available in Final Fantasy XIV: ARR in the future? I'm a huge fan of the game, but sometimes I like to do alot of solo missions but I would like to see more content. Will there be any plans for solo: Dungeons, Primals and perhaps a specific solo challenge mode?

Jobs like: Red Mage, Blue Mage which arent specific enough for parties could be a solo only job... Just for thought!
