We know all of this already:
There is not going to be a remake of FF7 for PS3. Square has even said that they will not remake FF7 until Sony makes a Playstation that isn't backwards-compatible all the way to PSX games.
There are going to be four sequels/spinoffs of Final Fantasy 7. The subtitles of each all consist of two words (not counting the word "of" in DC, simply because that wouldn't be capitalized anyway), the first starting with one of the first letters of the alphabet (A, B, C, and D for Advent Children, Before Crisis, Crisis Core, and Dirge of Cerberus respectively) and the second being the letter C.
