Keep in mind they are also going to be releasing a smartphone port of it - I'm not sure if it uses the same servers as PC though, but I don't see why not. For me FFXI was so amazing for a lot of years, especially during the first 3-5 years of its life. It's a little sad that it's nearing the end of its life, but I moved on a long time ago. I'm kind of surprised the PS2 version has been supported for so long, I mean it pretty much runs well on a toaster of a PC so I'm not sure why people never migrated over.
Except for Square it has been their most profitable Final Fantasy, so I don't think they share the same sentiment.
