So we now have the first emote seen so far: the chainsword held up high in the air. View: http://www.youtube.com/watch?v=PcbCtCTj6_I
Eldar dance = you die..sooo sure! Slaanesh has dancers. Nurgle was in the Thriller video. Tzeentch is always trying to change things up. Found a video for Khorne dancers: View: https://www.youtube.com/watch?v=jxi2dwXHJZY Orks would probably dance if it was violent and loud- mosh pit - then would end in a fight -mosh pit. Ultramarines obviously ball dance, I imagine Dark Angels dance like snoopy characters listening to saftey dance.

Faction based emotes would add much fluff to the game, for example a SpaceWolf should (in my opinion) scream more brutish "For the Allfather" or "For Russ" than your avaerage posh UltraMarine ... do they even scream or merly articulate a well sung battle hymn
I would love to see an emote to take off your helmet and another to put it back on again. It's not much, but I've wanted to see that for years.
taking of your helmet will be an option ^^ but do not know if on the fly or you have to chose prespawn
