This contains spoilers to the end of XIII. Couldn't fit it into the title.
What do you think are the chances that the "figure" could be either Fang or Vanille? Versus' logo has a sleeping woman in front of a very familiar image (if you've played FFXIII). Do you think Fang or Vanille will be involved in some way? The newest Versus XIII Trailer showed a woman who fought with a staff/lance - the same type of weapon Fang uses, being the traditional Dragoon character of XIII.
Another thing to think about is that the figure the trailers talk about could actually be Cocoon itself, frozen in time.
