I think there's a difference b/w CT being remade, and others games being remade.
First off, I think the only games we can really talk about being remade are RPG's. Stuff like Super Dodgeball, etc being remade don't count in my book.
With that being said, I don't know of any RPG being remade. The only possible one that there are rumors of is FFVII. Whether I agree with that or not, here's what makes it different. One, it has a MUCH larger cult following. Two, since its really a game within a series, there's no room for sequels, unlike the Chrono series. (I'm ignoring the first person shooter crap that's coming form Dirge of Cerebus). Where in the Chrono Series can become bigger by making a sequel, FFVII can't.
I think graphics has a lot to do with this as well. I think people came to love the sprite-action of CT, with the top down view. I personally wouldn't want to see this changed, which it obviously would be in a remake. FFVII, on the other hand, wasn't really about the graphics. No one really fell in love with the blocky, 4 colored characters. Updated graphics for the game wouldn't hurt it in the slightest.
