Someone at Disney was paying more attention than folks at LucasArts. This is good stuff.
The (other) amazing thing is the XWing/Tie Fighter releases are based on the special edition CD ROM version and not the releases using the XWing vs Tie Fighter engines. While the rerelease updated the graphics by adding textures (which, honestly, destroyed some of the character), some very important things were lost. Most notably, the game traded in the dynamic midis for generic digital versions of the common Star Wars music playing off the disc. If this is really what they're using, someone at Disney really gets what made these special.
The only thing they can (and I think should) do is increase the resolution on the polygons. Anything 2D, leave it (including cockpits), but make those flat polygons shine.
