I think an HD overhaul is great for bringing exposure to the series and getting more people to play the games.
People know have never played an Infinity Engine game probably won't know what mods to get or how to use them or might not even know they exist at all.
Plus if they can make the game mechanics a little easier to understand (let's face it, it was pretty tough to get into if you didn't know D&D) without dumbing down the core gameplay, then that would allow for a bigger audience as well.
Baldur's Gate is one of the best RPGs and one that in my opinion defines the genre; more people should be able to enjoy it.
