what new force powers do you think we'll see in kotor2, there are supposed to be alot of new powers.

Force absorb (stops shots?). I would also like to see a force absorb ala Jk2 multiplayer, force absorb that takes from the attack and adds to your force pool (a bit like yoda absorbing Dooku's attack in Ep2). Battle Meditation is a new force power (but small scale, were not talking about Bastila's ability here), uhm, Force Rage for dark side maybe, with increased speed and damage and decreased infliction upon yourself. Mind trick would be pretty cool. Dunno :D

Look at the thread Unofficial Kotor 2: Sith Lords FAQ. It pretty much sums all the new force powers that will be available.
