It to early to tell if GW2 will be the WoW killer since the game doesn't come out till 2011. So far all they have is two trailers that show us some new areas and races which is not much. For WoW the mountain goes so high before it starts to fall. What im trying to say is WoW is reaching it climax or at it with their new expansion pack coming out this summer. If you noticed how when BC came out the lvl cap was raised by 10 levels and new area (outlands) and when Northrend came along the lvl cap was raisedby1o levels againand a new area (northrend). Well what we know now is the lvl cap is going up only by 5 which is telling us one thing for certain they are running out of new content and ideas. Sure to new races are fun but nothing else is new. Once the new content stops pouring in people will loose intrest in the game. Thats where GW2 steps in and just might have a chance.
