So apparently derptemp6698, the guy who leaked info about two Mass effect DLCs, and was right on both accounts, has claimed to have gotten information about Skyrim's next DLc HEarthfire.
"Hearthfire, the next official game-add on for The Elder Scrolls V: Skyrim®, has arrived. For the first time in the Elder Scrolls universe, 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, trophy room, and more! With Hearthfire, the possibilities of what you can build are endless."
Is it true? maybe
Is it fake? maybe
but if it is real... all I can say is.... BOUT DAMN TIME BETHESDA.
