Well, we had our fun at speculation, but Bethesda dropped in this announcement video for Skyrim's next expansion, Hearthfire. No, it's not quite what you'd expect, as this is far from what Dawnguard was.
From their YouTube page:
"With this official add-on to The Elder Scrolls V: Skyrim, you can purchase land and build your own home from the ground up - from a simple one-room cottage to a sprawling compound complete with an armory, alchemy laboratory, stable, garden, and more. Use all-new tools like the drafting table and carpenter's workbench to transform quarried stone, clay, and sawn logs into structures and furnishings. Even transform your house into a home by adopting children."
Yes, we're going to be able to adopt kids. Unless I can use them as followers and send them to battle a dragon, no thanks.
Hearthfire hits Xbox LIVE on September 4th for the measly price of 400 MSP (that's $5 in real money).
