How will "World of Warcraft" Compete?

With the new release of Age of Conan, Tabula Rosa, and Warhammer online comming soon, does anyone have any ideas on how Blizzard is planning to compete with these new MMO'S ????

Well Tabula Rasa didn't get bad reviews but nothing extraordinary and there have been mixed opinions of Age of Conan (although overall it seems to be favorable). No MMO that came out seems to at all even threaten WoW.But seriously...
I remember similar statements with past MMO releases

Guild Wars is gonna pwn WoW, City of Villians is gonna pwn WoW, "RF Online is gonna pwn WoW, "Face of Mankind is gonna pwn WoW, Warhammer is gonna pwn WoW, and last but not least AoC is gonna pwn WoW, yet none of them has pwned WoW yet.

Blizzard doesn't rly need to compete atm but if it ever needed to it could easily compete using it's latest expansion WOTLK

 

would like to give a thorough answer for this question, but I'm feeling lazy so I will keep it short.

Age of Conan is out and it is pretty cool, but will probably not attract as many women players, since it is pretty sexist. This will prevent it from overtaking WoW. Also it has high HW requirements which will further erode its player base.

Tabula Rasa is probably trying to do too much and is likely to disappoint over the long term. Sci-fi MMOs are harder to do in general, I think. Also, it is supposedly hard to solo which is one of the secrets of WoW's success. None of the reviews have given any indication it has the chops to overtake WoW.

Warhammer Online has very little announced that sounds like a WoW killer. At best it sounds like it will be an AoC killer, but that might also be in doubt. Also, early speculation indicates the HW reqs will also be high.
