It's pretty much been assured that a Crystal remake isn't going to happen. With HG/SS including a majority of the Crystal features, a Crystal remake itself would be pretty much the same thing. Plus, there was never a Blue or Yellow Remake when FireRed and LeafGreen came out, so it's pretty much going to be the same in this case. With the upcoming Pokémon Black and White, Fifth Generation, it's pretty much official a Crystal remake won't take place.
