I hope not....but Oblivion taught me a valuable lesson....not to get my hopes up.
But If I have the option of say pushing a crate of barrels onto my target rather then stabbing him....I should be somewhat satisfied.
I also think that the thingy of the game is scanning your enviroment as well, deciding on an escape route, what can be used to your advantage etc.
An Assassins POV essentially.
My "what type of blow" comment is an exaguration but just looking from the screenshots it looks like there is one way to do things which is easy, and you can do other things like running around murdering everyone if you want to, but the games not designed for any other route. While you probably can drop a barrel on someone's head, I expect it to be only when it is designed for that to happen as the (or perhaps one of 3) easy way/s.
