We've been able to grab and manipulate objects in MW, OB, FO3, and FO:NV. I see no reason to think that we won't be able to in Skyrim.
To add to this, IDK how well developed it was in Morrowind, since when you go from Oblivion to Morrowind and find that dice rolls are factored into hit chance, you conclude that it kinda svcks (I'm not talking about the game in general, just that one mechanic, and if you disagree with me, I really don't care). Oblivion had pretty good manipulation of items, abate the fact that the collision detection in the meshes were kind of simplified (which is why katanas could roll) and bodies were really glitchy when it came to manipulating them. Fallout 3 improved on it and made the collision detection in the items meshes much more realistic and pretty much fixed moving bodies around. New Vegas improved on the bodies even further by adding in mechanics (where you would function as being over-encumbered when moving the body) as well as fine-tuning the movement of bodies in general. There was even a sub quest where you had to retrieve a ranger's body and carry it to a safe location.
I'm expecting them to define it even further this time around.
