When a game gets "remastered", I'm always a bit worried that it might either turn out as a poor porting or as a disrespectful remake
(changing is ok as long as its changes are optional). I think especially 5th gen videogames need remasters, because, most of the time, their graphics (and even controls) haven't aged well :\
So here's my list (in alphabetical order):
-Devilman (I'd probably do it myself if I had the right 3d models and animations
);
-The Last Ninja series (System 3 is going to kickstart it soon
).
-Legacy of Kain: Blood Omen (fans are already taking care of it);
-Legacy of Kain: Soul Reaver (though the dreamcast version is already good enough);
-Metal Gear Solid (the maps are actually fine, the problem is their faces look like masks
);
-Resident Evil 2 (Capcom is working on a remake, but it's supposed to be respectful, so I may like it);
-Shenmue I & II (hopefully they'll also translate them in more languages, or else it won't help much SIII);
-Silent Hill;
-Tekken 2;
