In their ongoing court battle with Interplay over the licensing of the Fallout IP, Bethesday may have inadvertently revealed
the existence of an MMO, as was submitted to court by the Elder Scrolls developer/publisher during proceedings.
Legal documents describe the product, which has apparently been in development for more than three years, as a "World of WarCraft type MMO" with a development crew of close to a hundred people and costing a ridiculous amount of money.
It's unlikely the game is an MMO based on the Fallout IP as that's the very reason they're in court; Interplay own the MMO dev rights to that franchise, essentially leaving The Elder Scrolls as the likely candidate. Add to this comments made last year by Bethesda the series would indeed continue along with the purchase of the domain www.elderscrollsonline.com and you pretty much have enough evidence.
