That sort of explains everything doesn’t it?  Bethesda says…

Hearthfire allows you to purchase land and build your own home from the ground up – from a simple one-room cottage to a sprawling compound complete with armory, alchemy laboratory, and more. Choose your land, customize your house, guard it from unwanted visitors, and turn your house into a home by adopting children.

Hearthfire will be available for download for 400 Microsoft Points on Xbox LIVE® on September 4.

When I first got the email this morning I thought they were announcing some new exciting DLC add-on pack, which I figured was odd considering the last update was just released a short time ago and was rather extensive.  This works just as well though.  A little end-game content never hurt anyone.  For those that don’t know, end-game content means for players that have pretty much seen all their is to see in a game, things like this keep them coming back for more.
