The will swell again a little with the demise of Warhammer Online and the constant flow out the door from WOW. Wow in particular is getting really stupid fighting pandas I dread to think what will be next its become a bit of a joke. The thing that keeps an mmo alive is new content a lot of the other games dont add anything for very long periods of time and you are doing the same old stuff over and over. GW2 may well not be the best mmo in the world but there is always something to do. Others should take note.
