Why Do SE Refuse to Remake FF VII?

[Sorcery]

Pfft, the game would sell amazingly well, all you have to do is look at PSN's most downloaded games every week to figure that out. Week in and week out, Final Fantasy VII is one of the top 5 downloads.

I don't think they want to do it because of fears that they'll make fans unhappy. Do you add more content? Do you add voice acting? Do you keep everything the same except for the graphics? Not all remakes are successful or better than the original.
