Correct.

Players can still play as classes in the future, which means classes are not replaced by jobs. Therefore, if you want flexibility, you can stay with classes without problems. On the other hand, if you want specific expert actions or equipments, you may need to put the job title on to be allowed to use those. This is why SE said, players can use classes in small party for daily leves or SP-gain purposes. For big events or fighting HNM, players will need full party and expert jobs to handle more difficult battles and situations.

Like I said, based on the released info, this class/job concept is essentially the same with what we have now. What SE doing is just give more hints to let players know what roles/jobs they can be based on the classes by setting some bonus and limitations corresponding to specific roles/jobs.
