Horizontal progression would be more like adding new power sets, pool powers and enhancement sets, which they are already doing. I could also see them adding additional TYPES of Incarnate powers for certain categories like Lore or Judgement to fill out different character concepts, but unless they have a means to make content even more challenging I'm not sure they will be adding the higher tier Incarnate powers past Hybrid.

I get what you are saying, but I wouldn't consider new alternatives to be "progression", as they're fundamentally zero-sum.
