Bringing this thread back to life, as Neverwinter Nights Enhanced was just released a few days ago. I bought it, and from an end-user perspective it doesn't feel any different than what I remember playing years ago, although they supposedly tweaked the game to work with up to 4K resolution monitors.
For me, the biggest benefit is that it is also available on Mac, except for the toolset. That means if I ever get back into NWN, I could boot into Windows to build, or use a virtual machine, but play on my main machine. I have started playing through the official campaign again, just to refresh my memory.
From reading reviews, Beamdog is viewing this as more of a development platform than anything. We'll see if they live up to it, but they say there are continuing to enhance the game going forward. They've already released a preview of a new Aribeth model, and plan to enhance other models in the game too to be more advanced. I suspect we will also see them sell some new premium modules, too.
Here's a preview of the new Aribeth model:

Scroll down on the page to see the old next to the new. Not sure I like the look, but it does show off what might be possible.
