There is no way in hell there will be a LOTR remake any time soon. Like them or not (I like them), they have become pretty iconic movies and are still fresh in a lot of peoples' minds.
The last thing the world needs is more remakes. I was just thinking yesterday about how stagnant Hollywood has become. A majority of hit movies are either sequels/prequels, remakes, or based on already popular source material like old comics. I'm not saying all of these movies are bad, but let's also have more new ideas.
