If you haven't seen yet, apparently mounted combat (swords and bows only at this point) is coming to Skyrim:
While I'm over the moon about the possibility, I wonder if this (and the previous patch allowing new kill cams and kinect shouts) is any indication that we will be receiving some of the more hefty changes (spears, seasonal foliage etc) showed off by Betheesda once the Dawnguard expansion hits? Sure, we will likely find out in about a week, but it's fun to speculate ;)
Which features would you want from the list? Flying vampires? Levitation?
