Game Informer's June 2012 Cover Reveal shows the next issue of the magazine will offer the official unveiling of The Elder Scrolls Online, finally fulfilling long-time speculation that Bethesda would one day create an MMO based on their popular RPG series. They say the game will come to Windows and OS X next year, and that a teaser trailer a screenshot will be posted tomorrow. Here's what they reveal so far:

Developed by the team at Zenimax Online Studios, The Elder Scrolls Online merges the unmatched exploration of rich worlds that the franchise is known for with the scale and social aspects of a massively multiplayer online role-playing game. Players will discover an entirely new chapter of Elder Scrolls history in this ambitious world, set a millennium before the events of Skyrim as the daedric prince Molag Bal tries to pull all of Tamriel into his demonic realm.

"It will be extremely rewarding finally to unveil what we have been developing the last several years," said game director and MMO veteran Matt Firor, whose previous work includes Mythic's well-received Dark Age of Camelot. "The entire team is committed to creating the best MMO ever made – and one that is worthy of The Elder Scrolls franchise."

An in-depth look at everything from solo questing to public dungeons awaits in our enormous June cover story – as well as a peek at the player-driven PvP conflict that pits the three player factions against each other in open-world warfare over the province of Cyrodiil and the Emperor's throne itself.
