I don't think mega servers are something WoW would win with. Too many people would literally clog the social aspect of the game. You don't want that in a mmo. If you want something similar, head over the almost-permanent "full" servers on the game. It should give you an idea of what would happen if these mega realms were merged with all the other high/med and low servers.
