I personally see the Barbarian as a Primal Defender and Druid and a Primal Hybrid (Striker/Controller).
They both have a lot of Stances that grant them various bonuses to speed, damage, attack, and defenses.
The Druid might end up like the Ranger and be split in two. But unlike the ranger; only one half with be striker, the other will be controller. Something like a bear armed CHA vs AC Twin Strike at will and a WIS vs Reflex Wind based Thunderwave. But no Quarry or Orb to back it up.
