At least I can confirm that Radon Labs has polished the gamne in a lot of places.
To me, the experience was nearly as good as in Drakensang, but I haven't played too far into the game - not further then the demo, in fact. THe only difference is that I know what comes directly after the end of the demo ...

But that is predictable from the demo's end as well ...

Personally, I had indeed the impression as if the social interaction was enhanced a bit more. Which is actually something I'm looking forward to.
