I'd love to see Mark and Recall again, I'm quite disappointed that they were gone in Oblivion.
I would assume they took out Mark/Recall because fast travel almost, but not quite, made it irrelavant. Sure, you couldn't quite load yourself up with 5,000 pounds of gear and away you go, but if you carried just the right amount you could FT to a city and walk to the merchant or your house.
Since it seems FT or a variation of it will be in Skyrim I don't see it coming back, but I wish it would. I really liked it.
I hope you have a better option to drag/carry bodies. That way I wouldn't have to look at Glathir's body lying naked in the street after I frenzied him and the guards killed him for me. Boy was he annoying. I could have dragged his body to a corner where I didn't have to look at him. Or the guards could have cleaned up their mess.
EDIT: Maybe allow you to fast travel to your house (if you buy one) so you can drop off your loot and sell at your leisure.
