I think your being a bit hard on 3D graphics. You used an extreme example of how bad 3D can look in the hands of incompetent artists. The 3D in MGS2 or GT3 is FAR superior to the examples you have used and is almost photo realistic in GT's case.
I too love the charm of 2D but I also love 3D games.
3D opens up possiblities that could never have been done in 2D.
