Agree - while I slightly end up preferring the original houses a little more, I also greatly enjoy good IP houses.  My 3 favorite houses last year were Graveyard Games, Universal Monsters, and House of 1000 Corpses - 1 complete IP, 1 partial IP (characters, not necessarily story), and 1 complete original).  Plus, it's awfully difficult to speculate about original houses since the possibilities are literally endless so there's no real jumping off point except for sequels - that's why speculation surrounds IPs more than originals I think.  But I certainly wouldn't mistake that for a lack of enthusiasm for originals in the slightest.  In one of Legacy's clues, I ended up at a potential Jack the Ripper house/scarezone.  I'd be absolutely thrilled for something like that.  But again, it's tough to speculate those because there's no real starting spot for the most part.
