You're right. Now I'm just confused. (Recruitment)

As for the designs, I think the white and gold Vex are the newer design because they're all shiny. It's simple reasoning but the best designs only need simple reasoning. Knowing Bungie though, I could almost think they switched them around (multiple times) on purpose to create an out-of-game confusion that reinforces how transcendent and inscrutable the Vex are.

The 'older' ones remind me of bronze-age ... stuff, maybe even steampunk, where as the silver/white and gold gives me a more sci-fi feel.
