The point of FR/LG (and really all of the remakes) was to get all the pokemon you couldn't find in R/S/E. And because we already have a way to find every pokemon in Gen 6 games, there's no point to remake them. Yet.
With that said, I wouldn't mind a remake of Colosseum and XD GoD. They could add the Stadium minigames and other challenges, make a postgame where you can catch wild pokemon, and you have yourself a game. Hell, they could make them for the WiiU, and allow online play with the 3DS ones.
