I'd have to disagree, maybe 10 years from now. There just wouldn't be enough of a difference if it was remade today. Oblivion is more popular and well known than Morrowind (I'm not saying it's better, that's down to individual taste). Even in 10 years, who's going to remember or even be bothered about Morrowind (except for its fans). Take FF7 that would do really well if they remade it, after 13 years it's still very popular and someone told me you can get it at the Playstation store, I doubt Morrowind will be remebered much 13 years from now.
I agree that if it were ever remade that they need to wait a bit first. It would be neat if maybe on the 20th anniversary, they released a remake of the game with whatever the existing engine is, but I'm not sure it would be worth the effort. Now, many have mentioned, "what's the point of a project like this with all the mods out there?" Well, first off, remaking the game in the future would still look better then a modded Morrowind. Also, something that hasn't really been mentioned is how bad the performance of a modded Morrowind is, not to mention incredible buggy. The game is incredible CPU intensive because of its age and the engine is incapable of offsetting some of the load to the video card. Playing Morrowind with these fixes would be incredible. Also, adding things like physics, etc would be nice.
Now I do have to completely disagree with your comments,
I doubt Morrowind will be remebered much 13 years from now.
Morrowind is about 8 years old right now and I can go into a random store like Walmart or Bestbuy, and I bet I'll find a copy of Morrowind on the shelf despite it's age. How many games that old can you say that about?
