What I don't understand is that they are doing this to themselves. Of course remaking the entire game in a scale 3d environment would be insane.
I had just assumed they where going to make new high res 2d backgrounds and better models for each scale, re-render all the cutscenes and call it a day.
Because a full-fledged from-the-ground-up modernized remake is going to attract a larger market share.
"Enhanced ports" and "remasters" virtually never pull the weight that hardcore fans often expect they will. Even Ocarina of Time 3D failed to bring the 3DS out of its early-days rut.
