Didn't they say in the "Beginning" video that you'd face 4 wraith commanders? I assume that's what the other guys are, the King of the Wild Hunt being the 4th one.
3 commanders (4 with the King) and... 3 zones. Shit, I can even see how the story's probably gonna be structured now... Please, don't do it the way I think you might be doing it, RED. We kinda have BioWare for that.
Anyway, on topic, this thread seems like a good idea, though putting the screenshots from different categories in spoiler tags might work better (as someone suggested).
