Ace! Nothing better than getting a kill by beaning someone with a 'nade.
Sounds like customisable HUD might be in, this is inline with elements seeming to have moved from build-to-build. Obviously it could also be explained by the fact that things like this change throughout development.
He's such a tease. :D
Oooooh! Now this is interesting, suggests there's more to the differing colours of Prometheans than just rank. We've seen orange and blue/purple so far, I'd not read too much into it assuming they would just be different ranks of the same faction. David's comment would suggest there's more to it than that.
It could be orange for The Didact and blue for Mater Builder perhaps? Maybe blue could be Cortana controlled if she gets herself into the Requiem systems. ForwardUntoDawn.com have gone into great detail about potential Halo 4 antagonists - essentially it could be The Didact, The Master Builder, Cortana or 343 Guilty Spark.
It's really cool that 343i staff are able to do this, so many developers are locked down and shrouded in secrecy, so you never get this kind of interaction with fans. This is the sort of thing you might expect from a tiny indie developer not one of the largest in the industry. Well played, 343.
