Several of the better remakes, like the DS ones were still largely helmed by the people who worked on the game. While VII still has Nomura and Kitase, I would guess many fans were not as pleased with their foray into the Compilation and hope that having more of the core team that's missing like Sakaguchi and Masato Kato would be able to keep the remake more faithful. Especially since Kitase has said he would probably be making lots of changes if he did direct a remake of VII. The Compilation has also kind of killed the likelihood of a faithful VII remake, as many of the newer VII fans got into the series through Crisis Core and Dirge of Cerberus, and you can't exactly blow them off because the older fans want nothing to do with Genesis and DeepGround.
