We got a melee dps and a magic caster dps in storm blood. Very high chance we will get a tank and a healer before we get another dps, of which if we do, it should be a ranged physical dps (like Bard or Machinist).

That said, tank is unknown, healer could be Geomancer, ranged physical dps could be a Dancer/Dirvish using Chakrams and thrown weapons. I can't imagine them adding another dps though in 5.0 considering how there's 3 healers, 3 ranks, but like 10 dps jobs.
