Here is a very long but fascinating first impression article describing the first 25 hours of Final Fantasy XIII.  Awesome!  The author describes each of the main characters, the battle system, the story technical aspects (no spoilers), the pacing, the linearity, the level disign, the enemies, the bosses, etc. and why he liked or disliked them in great detail.  This article was so interesting to read that I had to bookmark it because I know I will want to read it again before the March release date.  Contains No real spoilers.

Enjoy!
