While I don't think it will kill WoW I do believe that it has the parietal to carve it's own type of MMO out that could appeal to WoW players and RPG players. From what I heard, the game is very story driven. It supposedly has a different storyline for each class and faction based stories on each planet. I am not talking about little quests, I mean a story. Those things that take god knows how long to complete. Add to that the full voice acting and things like space battles there is a lot going for it. Something for story driven people.
