Probably because you were just reading chat and forum posts.
I never believed a remake would happen purely because I don't think it's going to be profitable if developed the way fans want it to be, and also because I don't want one. However, on the livestream, the manner in which Hashimoto was presenting, the way they popped out the FF7 logo, talking about history and returns, I actually thought for a moment, in half-disbelief, "Are they actually doing it?!"
I think what caught a lot of people, perhaps even those who didn't want a remake or didn't think a remake would happen, is just that one moment where we wanted to believe. Of course, it sounds silly, but a lot of us are still fans because we still feel something great can happen.
