Frankly I don't really care what specific house sits on the throne, since most of the houses will be -blam!-ed by the end anyway.
Since Stannis is almost guaranteed to die, I'm hoping Sansa.
As long as the North wins independence, I really don't care - well, as long as it's not the Lannisters (though maybe if it were a Tyrion who had gotten over his drinking and whoring).
