Due to Bethesda's rumored exclusivity agreement with XBOX, one can conclude that the PC and PS3 versions will be available sometime in October. Build your dream house in Skyrim, hire a stewart, bard, move in your wife, and even adopt kids. Protect your Tamriel home from beasts and savages who may cross your path.
In fairness I won't be wasting time with dlc even if it does reach PC, since it's a blatent copy of a mod that's been free on the modders nexus site for many months now
