Actually, it pretty much is an analogous situation. 1, 2 and 4 on the PSP had their textures, sprites and backgrounds enhanced, so that they fit the HD resolution. X/X-2 is getting the same, the graphics were 3D from the get-go, only textures and character models are given a higher resolution. A similar remake for the PS1-era games would require them to completely redraw the prerendered backgrounds, making work on such a remake far more costly.
