I know that it is hard to believe that anything bad could possibly happen to WoW, but I have a bit of my own logic to throw into the equation. I am not really a fanboy of WoW, or any other game for that matter. Seeing the trend of "RIFT vs. WoW" and "I am quitting WoW" threads popping up recently, I decided to post a poll yesterday in the forums. The poll was active for the better part of 8 hours before the mods closed it down, and to be honest, I was glad they did because the fanboys and trolls were starting to creep in and turn it into a flame thread. The poll managed to rack up 205 total votes and of those votes, 33.66% of the people polled were leaving WoW. While I can't say that this a good reflection of the entire WoW community, I did think is was interesting.
The results can be found here:

The question at hand, imo, is not if WoW will die, but what would Blizzard be willing to change or willing to do to keep from losing 1/3 of it's customer base?
I must also state that the poll can not factor in the unknown variable of "I am leaving WoW for <game>" people that eventually end up returning to WoW after said game goes bust. I am looking at you former Aion players as a current reference.
