An agreement has been reached which means a PlayStation Plus subscription won't be necessary in order to play The Elder Scrolls Online on the PS4.
Talks had been ongoing about this very issue, with ZeniMax previously unsure about a positive outcome. The issue being discussed was PS4 online gaming requiring a PlayStation Plus subscription, which means you would have to pay two subscriptions to play the game.
"A PlayStation Plus membership is not required to play The Elder Scrolls Online," declared Matt Firor on the PlayStation Blog. Firor is working for ZeniMax as a game director on The Elder Scrolls Online.
Firor also revealed what this mean for the fees PS4 gamers would have to pay to play the game: "PS4 players will only be required to pay the same monthly subscription associated with The Elder Scrolls Online that PC and Mac users will pay - nothing more."
This will be seen as great news for Sony, as it's expected that Microsoft will still enforce an Xbox Live Gold subscription in order to play The Elder Scrolls Online on Xbox One.
The game is due to release on the PC/Mac first, currently scheduled for launch on the 4th of Aptil 2014. The PS4/Xbox One release will happen during June, but no specific date has been issued yet by ZeniMax.
