[dev1033] Class name changes -> Specialization/Talent Trees Into Classic FF Classes

So would the Dark Knight be using a sword and shield too?

As far as I understand it, not really. You would be using a sword-type weapon, be it a great sword or a sycthe-melee weapon that used sword skill. You would still gain sword points towards raising your base GLD class, and perhaps points towards raising your base THM class, while still gaining points towards your DRK advanced class.

If you decide that you want to switch to PLD, then the abilities and skill points earned towards your base GLD class while leveling DRK would still remain, but your PLD advance class and 'tree' would be at the minimum (or lvl 1). But you would still have access to all the base GLD skill you had obtained while leveling your PLD.

Of course, if you wanted to use a sword and shield as a DRK and use pure GLD skills augmented by the DRK 'tree' you could. You could probably even tank... but elitist groups and endgame content wouldn't want you to. But you could if you wanted to. Not optimal, but viable.... and who knows, maybe even the best way to bend the rules (Drk/nin Kraken club?).
At least that is my understanding of the system.
