Bethesda has just announced plans to bring The Elder Scrolls Online to the PlayStation 4 and Xbox One in spring 2014. Sony confirmed during its conference at E3 tonight that the PS4 will be the first platform (or possibly just the first console -- it's unclear) on which the ESO beta will be available. The game was slated to release on PC this fall, but the press release (and a tweet from Bethesda's Pete Hines) seems to imply that the PC launch window has also been delayed to next spring: "The game will launch on these consoles, in addition to the previously announced PC and Mac versions, in Spring 2014."
ZeniMax has also today released a brand-new trailer to coincide with the announcement; we've tucked it behind the break.
