Evil Dead remake isn't happening, last I heard. And of all those movies you listed, I would bet Halloween gets the treatment first, because there's already been rumblings. I just saw the original Nightmare on my local college campus, and even though I've probably seen it a 100 times, it still strikes me as one of the greatest horror films of all time, so I would really be upset at a remake. No one can play Freddy except Robert Englund.
I would add "Phantasm" to that list, too. I wouldn't be surprised to see a remake. And "Pumpkinhead."
Getting back to "The Hills Have Eyes," I just realized that the director of the remake directed "High Tension," so I'm a little more interested. The first half of that film, before
Warning: Spoiler! (Click to show)the big twist
has some of the most suspensful sequences I've seen in a while, and the original "Hills" thrives off of suspense. So we'll see.
