as to job direction...

pup: the only things we can be absoutely certain of; whm AI will never be fixed, scanner will never be made to function, rdm pup will remain capped at level 72 and harlequin at 50.

Beast: all depends on where the majority of new content is placed. If it's in Abyssea then all we'll get is new jugs, outside then we might get a tame or charm upgrade

Bard: a new tier to haste and elegy, if we are lucky, threnody II; oh, we'll also get another tier of requiem... that every mob over level 65 is still immune to.

Thief: Mug II, essentially Mug with shield/weapon bash included. Gil Finder II, very handy since nothing in Abyssea HAS gil.

Dancer: honestly? expect a nerf.

Paladin: expect some type of JA that allows it to absorb hate from the party or else suppress hate gain by other party members; it won't work and DD will just use it as an excuse to go all out on damage... kinda like they do now in abyssea.

monk: JA Grapple, causes a bind effect with DoT-on par with Bio II, reduces enemy evasion on par with gravity

ranger: lots of needs, but I would only expect some new ammo recipies, with relatively easy ingredients. Oh, and maybe a new end-game level X-bow

corsair: SE has no idea how to make this a loved job. expect reduced price on cards and maybe something that allows you to barrage.

scholar: raisega, warpga

red mage: just another tier of elemental nukes and 1 more level of cure, MAYBE an enhanced stoneskin

white mage: a JA that allows you to remove weakness from 1 party member... by taking it on yourself. Usable only when you don't have weakness, so 5 minute recast

ninja: Utsusemi: San, 'nuff said

warrior: some type of tier 2 defender

black mage: Curse, kinda like break (a 15 second earth-based sleep), this'll essentially be like a 15 second Bad Breath

blue mage: some type of revampped 2 hour, otherwise just some heavy-duty spells, maybe 1 for much higher defense.

dark: a native refresh trait, a couple of dark based debuffs

sam: regain, prolly 1/tic

dragoon: upgrade to wyvern defense, magic defense and melee damage, nothing for the master

summoner: expect something on your bloodpact timers. Since it won't be instantaneous, expect the summoners to still bitch about it. also, expect a new avatar, prolly bahamut, at 99 only, and he'll be along the lines of Odin/Alexander- a 1 and done.
