There's also some further details at GameSpot, including info on the next couple of modules:

The Orrery quest will see gamers set out to repair a Dwarven Orrery (an apparatus that shows the relative movements of heavenly bodies in the Solar System). Once completed, players will have access to powers based on the world's lunar cycles. Said powers could possibly be lycanthropy, as werewolves were featured in The Elder Scrolls III: Morrowind expansion Bloodmoon.

The second will be the inclusion of the Wizard's Tower, which will serve as new digs to call "home sweet home." However, it is unclear whether the tower will be part of a quest, or just new property that can be acquired. Players who set up shop in the Tower will be able to grow herbs, make spells, summon atronachs, and perform other magically terrific tasks.
