I wasn't overly impressed by the combat in that giant Bomb vid, mostly due to the gamepaly balance. It seems too easy, especially if you take in consideration that those guys were playing the game like untrained monkeys, that they were mostly leaving the companions uncontrolled and that Bioware included the now standard, dying is meaningless mechanic. I imagine the combat will be more rewarding for players who like to leave everything to the AI rather than the ones that control everything BG style. The only thing I did like in the vid was the interface from the inventory to the colored circles.
All that said, I'll probably buy it when I can get it for 20
