I can't think of any good choices off the top of my head, but there's one thing that should be true of the archetypes in the first little bit.
You should focus on getting archetypes out for classes that don't have as many "swapable packages" built in. Like how the Sorcerer has bloodlines and the Wizard has schools and the cleric has domains, and the druid has a choice of a few nature bonds and so on, so those classes don't need archetypes as urgently as say, fighter or barbarian.
That's my 2 cents anyways.
