I understand the economic implications of not making the theoretical 500k, but much of the hype seems to revolve around a need to be playing the most popular MMO.
It's doubtful there will ever be another WoW where a single game can so completely dominate the genre. In this post WoW era MMOs will have to share the available pool of subscribers. With whatever amount of subscriber-ship TOR actually requires, if they are able to provide necessary new content and the occasional expac I think the real TOR fans will be happy. Then gaming fotm crowd may continue to bounce from game to game with minimal effect to TOR.
