I don't like getting into the business end of such beautiful games, but how long do you think Final Fantasy will last?
Can it last forever or is it already going down-hill?
Perhaps you even think its improving?

For me I believe square enix aren't doing anything wrong, but they are beginning to follow in the direction of the mainstream gaming industry.
For example with recent advances in realistic graphics, the attraction with FF XIII was how great the graphics were and how action packed the game-play was leaving little regard to what the plot/story/setting was. Well this is what I observed from the media coverage of FF XIII before it was released.
Also, I'm not to pushed on the idea of playing FF online, and would hope SE don't make too many more online installments.
