Not really, how many times did people say WoW would kill FFXI?

"WoW is going into Beta, FFXI is done for."

*FFXI survives and actually gets a population boost*

"WoW is being released, FFXI is done for."

*FFXI is still going strong 7 years later.*

Nothing is ever "up against the clock", even in this day and age - You either play a game or you don't, there's no mass exoduses just because something new comes out, people learned this the hardway with Aion.
