It doesn't have a central eye, the whole head is one glowing unit. It does not have a head crest or chest orb, and is not a biped but has multiple leg things floating about. The guns are multi-barrel gatling style weapons that don't seem consistent with the future style of the Vex weapons seen so far. No vex so far has back fins.

Looks pretty Vex-ish to me. Central eye is there, the surround has a similar shape to the crest. As for the rest I don't personally see them as being at a remove from what's been shown of the Vex so far, but I see how you can take it differently.

That boss does not seem to have much in common with the Vex design language. A rogue Human security device perhaps? Or a dragon of the Darkness?

I disagree, what is it that makes you say that? To me it has a cyclopean quality which fits the Vex design appropriately.

I think I'm looking forward to exploring Venus the most out of all the areas so far (mostly due to the color palette and architecture)

Same here, of the competitive maps available in the beta, I found Venus to be the most fascinating. Can't wait to explore that planet.

Bring on the 9th!

I'm excited to explore those caves with the lightning ceilings!

These trailers make me mad. I want to play Destiny and these trailers make it hard to stop thinking about Destiny. Arrgh. Back to work...
