With WoD in a month, what do you feel will happen in to FF14's population?

I didn't forget that. Like I said, many players left after Cata/MoP. A lot of which are currently FFXIV players.
If the expansion brings everything it promises, expect the players to follow.
Not to mention that by the time players have raids in full clear with the equip they need, the first major patch usually roll's around with more content.

Yes. i agree entirely. This is the most important part i believe. The fact of the matter is that WoW is now level 100. So that's a really serious product for another game to compete with. That's simply how large that game has become with a subscription like 6 million.
