We’re less than 24 hours away from unleashing Skyrim’s next add-on Dragonborn on Xbox LIVE. It’s one of our most ambitious add-ons ever and we’re excited for everyone to play it.

We’re also happy to announce Dragonborn will be available on PS3 and PC early next year.

The support from Skyrim fans over the last year has been amazing, and it’s driven us to support Skyrim more than any game we’ve ever released – including free content updates, modding tools like the Creation Kit and the Skyrim Workshop, and our add-ons, Dawnguard and Hearthfire.

And we’re still not done – we look forward to sharing more Skyrim news next year!
