Wow. I was expecting Collectors for MP at some point, but this was much bigger then anything I expected. And with any luck, we'll see them in single-player DLC sometime soon (maybe Omega, maybe something else). Harbinger's VO and possible in-game appearance is just the icing on a very large cake. The only disquieting note is what looks like a new Praetorian one-hit-kill.

Also, turian with rocket boots.

(I'm still calling the playable volus as fake, though).
