Please use http://www.gamesas.com/topic/1320106-official-tes-multiplayerco-op-thread/ for discussing Elder Scrolls MMO possibilities.
As for myself, if it was free to play (or I was given a free subscription

) I'd happily try it out. I've had fun with some MMOs in the past (EverQuest when it came out, and Anarchy Online when it went F2P) but it's not a genre that I've really done much with.
