Source: Joystiq Recently on a Playstation blog post it has been confirmed that PS plus shall not be required to play Elder scrolls online and so to some it is a huge relief but despite all efforts Microsoft still refuse to not allow you to play gold to play the game but of course it may change so there is hope.
The Elder scrolls online is a MMO and so costs 15 pounds / dollars a month to play but new content is expected every few weeks and it is estimated to take 150 hours to do everything in one faction area so without any new stuff at launch you should have 500 plus hours of content already
Also to add there may be a bundle where you pay 60 pounds for example for a years worth of membership and it may be free to play or the cost may come down to boot.
EDIT
Can a nice friendly Mod fix the image ?
