SE said that if they decide to remake FFVII, it will take 5 years to do it. And in an interview, Kitase(i think) said that if they remake it, SE want Nomura to be the director, or something like that. These informations are examples that SE is thinking about it. If they aren't interseted in remaking FFVII, why they would waste their time thinking in an estimate of how many years they would need to do it? And why they would talk about Nomura as a director?
SE is interested in a remake. They just don't have time in the moment, because of other projects(FFVII:CC, FFVII:ACC, FFXIII Fabula Nova Crystalis, etc). When these projects are over, they will probably do it.
