I hope it has a fair bit of life left. And i'd like to see a new expansion. With the SoE story over i'm not sure how much longer i will play.
My hope is that FF11 is get a spin off one day set in unexplored lands that we havent seen (far east, mithra homeland ect) and maybe even in a different time, like how the ivalice alliance works. 11 has the most interesting world out of every FF by far.
