I don't think the general Elder scrolls player is going to be happy with a MMO version of their game. TES was about making the world yours. Kill a NPC they are dead in your world. Drop an item you can come back and pick it up 6 months later. Did you play the villian and murder an entire villiage while they slept? Or did you route the bandits that were ambushing travelers along the road.
How does that translate into an online game? Will your actions effect your world? What about other peoples actions?
This is the soul of The Elder Scrolls series. It's something that doesn't translate to a persistant online muliplayer game very well, if at all.
TES online will be hyped to no end. But I don't think it will be what people ultimately expect from the game.
That and when was the last time bethesda released a game without major bugs? The MMO community is ruthless when it comes to buggy software. the big B will be luck if they can have a stable client and server software ready for launch.
That being said. I don't think there is grounds for a "fight" between these two games. They will both survive even if launched on teh same day. If anything XIV will have a leg up by having a PS3 release, which opens the door to non PC gamers which there are a mega tonne of.
