I heard they're probably going to reboot it later (or possibly do another villain POV movie like Maleficent with that), just like Beauty and the Beast and The Jungle Book. It's just Disney's favorite thing to do now.
I don't really know how the Disney reboots are...different takes on old Anderson/Grimm/whatever fairy tales is one thing (I actually love Snow White: A Tale of Terror and Ever After), but I just have no desire to see another take from Disney in live action form. I was satisfied the first time and don't need them to do it again. I see no real 'nostalgia factor' to that for some reason, it just feels pointless to me. (Just my opinion though!)
I actually wouldn't mind a movie version of that....from someone other than Disney. Disney's Little Mermaid is fine and one of my favorites from them, but the real fairy tale has a bit more of a proper message behind it, darker or not.
I'm also tired of remake movies in general, especially for stuff that was already great to begin with and didn't really need it, but I don't see it stopping anytime soon, people always go to see them.
