Responding to the question of why the phrase "Remake" was specifically placed into the title, you can practically see co-director Tetsuya Nomura grinning from ear to ear. Nomura says that it was him who decided to use "Remake," and that there are "two meanings" (oh boy, this is like a Kingdom Hearts ending in real life).
Nomura says the first meaning deals with "quelling the doubt" that it would be a remaster; so he put "Remake" up there in neon lights to people would know it's legit. Nomura says "[he] can't answer" as to what the second meaning is right now, and to "ask [him] again in a couple of years," with a laugh. Boom, there it is.
Because commenters are no doubt going to be talking about the new Remake ending, tread lightly. I won't spoil it here, but suffice to say the wait for the next entry is going to be excruciating, if only to see how much the team deviates from the main storyline. According to producer Yoshinori Kitase, "the story of FF7 will continue as FF7 always has."
