"SE don't want to take the risk, because what if the fans don't like it?..."
Ehm, there are more than a hundred fans, working in the company, to fend off bad directions. But what bad directions can there possibly be, when ALL we ask (and only have been asking for) is an upgrade in the graphics. (ala ResidentEvil 1 vs ResidentEvil 4). The original songs included, with optional remixes like the ones in FF7AC - can be a plus, too.
I know about a dozen guys who wouldn't touch FF7, for its graphics; gamers spoiled by PS2 and PC games. My point is that with improved visuals, not only fans will buy it. It wouldn't be a stretch to say, that the number of customers will be minimum (and I mean minimum) 2x the original customers.
