Playing WoW currently because WAR isnt up yet.
When WAR goes live I will devote a lot of time leveling up various characters and trying to expereince the game.
I am not planning on cancelling my WoW subscription and I will be buying WotLK when it comes out too.
I will, on the other hand, be cancelling my EQ2 account and I cancelled my Conan account two weeks ago.
I have no problem managing my time between WAR and WoW, especially since WotLK wont be out til Oct/Nov.
I have almost ALWAYS had at least two MMOs subs going at the same time... so WAR and WoW will compliment each other nicely.
I wont talk about the lifetime sub I have for LotRO though...
