Yoshi made it pretty clear that they don't want to release any new jobs in patches going forward because it's so much work. If we did see SAM it wouldn't be until 4.0 at the earliest and even then I don't think we necessarily will... The game has an overabundance of physical DPS jobs now and desperately needs some new casters. I'm hoping they have preliminary designs for either RDM or BLU in the works already; RDM especially given how much it's been requested since jobs were added to XIV.
