I got an email saying that those who had purchased The Elder Scrolls Online, or The Elder Scrolls Online: Tamriel Unlimited could transfer their accounts to console for $20.
Fine print says that you can keep your account on PC as well as that on console, but progress does not synchronise. I managed to buy both the Xbox One & the PS4 versions for $20 each, through the one account.
Seems like a good deal, as the game is still only available for preorder, with the typical price being $79.
Ironically I just got an email to say I'm invited back for a "free weekend" :)
