Well, there was a lot in this video, and most of it flew past too fast to see :)
Force choke was shown, as was the "Force Persuade" dialogue option for the Sith character, shown here

Smuggler cover system shown

and a bounty hunter ability called "Electro dart"

The republic ship flying around inside the landing bay and firing looked pretty amazing :)
Absolute Confirmation from Video:
UI / Dialogue System
--Mass Effect -style dialog wheel with multiple dialog options.
--Mass Effect style response labels - what is written in the wheel is not necessarily what your character says verbatim, merely the 'gist' of it.
--Mass Effect style icons in the lower left of screen for group members.
--Complete UI screenshot available now, at much higher resolutions than previous hints of it. Radar confirmed, WoW-style icons for special abilities confirmed. Note what appears to be an experience bar in the bottom of the shot.
--Of particular note is the health system, which seems to be represented by blue and red bars for non-force-using classes, blue and yellow for force users. Red presumably being health, this would make blue an action bar of some sort, and yellow a Rogue-esque charging meter for special attacks.
--Existence of a KotOR-style "Persuade" dialog option confirmed (3:57). This provides strong evidence of a skill development system similar to KotOR, in my opinion.
--Existence of a combat log confirmed (3:38, upper left)
--Buff/debuff icons next to health bar confirmed for cover, being choked, etc.
--Existence of ability cooldowns confirmed, preventing multiple abilities from being spammed successively.
--Existence of a dice roll deciding who takes the lead in conversational choices confirmed (1:04). Unknown what factors influence it (Charisma? Level? Pure random?)
Classes / Abilities
--Existence of at least one Sith ability, "Channel Hatred", confirmed.
--Existence of at least one Bounty Hunter ability, "Electro Dart", confirmed (3:37).
--Dual wielding confirmed (even moreso, now, anyway).
--Sith lightsaber colors NOT restricted to red
--Existence of some sort of leaping ground smash ability confirmed for Sith (4:50)
--Existence of Force Choke (channeled) confirmed (officially, anyway) (5:14).
--Existence of "ranked" force powers confirmed (5:14), which would logically imply one receiving improved ranks of powers according to level and/or spec investment
Misc.
--Enemies appear to be divided into different tiers, undoubtedly describing their difficulty. Among those shown are "Grunt", "Fodder", and "Boss".
Let's talk video. What did YOU see!
