Nah, I see no point in pre-ordering the game before the release date is even known. Even then, I only pre-order it early if there's a limited edition I want. Otherwise might as well wait for a decent pre-order deal.

All of this is of course assuming I'm 100% sure I want the game. I'm not a big FF7 fan so in this game's case I'd wait even longer and watch enough gameplay footage to decide if I'll get it.
