IGN have an NS2 preview up. It’s mostly a quick overview of things we already know, but it does include a few new pieces of information. The most obvious is the Onos trailer below, showcasing the new run animation with a touch of Gorilla gorilla.

There’s also this paragraph on the Onos’s abilities in NS2:

So the new Onos in Natural Selection 2 have the following powers. There’s Gore, which is a melee attack where the Onos can slam his head into a target and even flight them around. Bone Shield makes blades come out of the Onos’ head, so when crouched down it protects the rest of his body from frontal attack. Then there’s Stomp, which can be used to send out a shockwave that disables structures that the Marine commander puts down.

IGN promise more alien trailers are coming in the near future, so we should probably pay attention or something. Check out the full preview!

Note: IGN are incorrect where they say the aliens do not have a commander. The aliens do have a commander in NS2.
