Yeah, I'm not sure what a "remaster" would entail. Just touching up the engine to accommodate higher resolutions? Not an entirely bad idea, because the core gameplay is still fun and works today. But they already did that for The First Decade IIRC, and there's a limit to how much you can upscale that without making even Mammoths look like ants. And any changes beyond that will probably affect gameplay, and then we're crossing into remake territory, rather than "remaster".
Much as I'd like a solid C&C game, in the age of MOBAs, I can see a number of ways in which they'd botch a remake. This is EA.
Hope they can do something with the cinematics, but not sure if they have the originals. Probably also change to the right click command way of doing things as people are pretty used to that these days.
