@Sykal,
you are correct in that it is "another human faction."
However, as far as I am aware, it is the only faction that is mech/battlesuit based, and is explicitly, I believe, intended to be melee heavy.
I say that because the featured uit is a flyer designed to get in close, and the support unit is designed to further minise damage taken of the flier, and maximise damage dealt.
And I am excited if this is the case.
Also, the picture showing the grail of life shows 2 new units, both holding what appear to be melee weapons.
A melee based race in a ranged dominant combat game...colour me intrigued.
edit: plus, look at Tibbles' gorgeous pictures. That looks like a great deal of bashing capable mech warrior to me.
