I think the MD games won't get a revamp for awhile. PMD3 came out right after DPP and right before HGSS (if I recall correctly) so right in the middle of the 3D overhaul but it's graphics never changed. Maybe because techinically it was the third in the Darkness/Time set but IDK. The graphics haven't changed much, I only remember Grovyle getting a color change being the only sprite change
@Roconza-Snap might be, I recall they made a Wii version or something
