Of all Pokemon games that would like a remake for sheer experience of it, not to mentions chance to apparently redeem themselves in a lot of people's minds, Ruby and Sapphire would be near the top. That's all they would be, anyway, since the first two sets of remakes served a more utilitary purpose, and Game Freak apparently made very close to everything available in XY aside from legends and starters.
I guess the problem is, though, is that the remakes tend to highlight how limited the current tech actually is, even though you'd think that would be the sparse source material talking. If we want a presentation-oriented version of Gen 3, XY's engine doesn't cut it. I don't know what I'm smoking that's making me say this, but I've never been big on the remakes to begin with beyond the novelty of carrying a Groudon through Kanto. They are, for the most part, so, so very far from the perfect nostalgia storms.
