I doubt FFXIV: ARR will ever be Free-to-Play. In fact a little bird told me that the Alpha is really a lot of fun to play. It looks, feels, and smells nice. All that and its only an Alpha. People have even said 1) It should be a Beta 2) The Alpha is nothing like any Alpha ever done before. Its as if the game is ready now.
That being said, an Alpha that is that good makes me think we are in for a real treat.
