I think we will see less cut and paste. Fallout 3 shows us that they are moving away from that.
Personally I don't think Fallout 3 showed us that at all. Sure, the towns were all quite different and the main points of interest were mostly unique. But many of the random caves, and buildings were in fact the same or made up of the same building pieces so they looked the same. So there was definitely not a lack of "cut and paste" going on in Fallout 3... and its hard to say that its drastically less then in Oblivion IMO.
With that said, any game that large is going to have recycled buildings and assets most then likely... so its not a huge issue or anything. However, I would like to see a few very unique and different dungeons and caves in Skyrim. Oblivion really only had two different looking themes for most of its caves/dungeons and after a few hours it got depressing not seeing anything different.
