Beamdog has made a name for itself by remastering previous Bioware titles like Baldur's Gate. It seems they are continuing with the streak too as they are now taking on another RPG from the developer's backlog.
It's been announced that Neverwinter Nights: Enhanced Edition is on its way very soon. There is no specific date for the game past the vague 'soon', but it's available for pre-order for $19.99. The game will see it support 4K, have scalable UI and see some graphical work. That being said, it doesn't look like any major work is going into overhauling or 'remastering' the dated graphics, so keep that in mind. As a nice added bonus, you'll be able to bring all your mods and previous save games with you into this version.
You can see it in action right here in this trailer.
