I'm pretty sure Samurai will be the next tank. I hope for a DPS, but I don't think it will be that, because with a DPS Samurai and a new tank using probably sword too, at least some sort of big blade, the two jobs will not be enough different. The next DPS will probably be Red Mage, and it would be nice if it's a melee DPS, using magic sword, some kind of magic fencer. For the Healer, maybe Dancer, but I don't play healer, so I don't have any wish for that kind of job.
