I've been keeping a watchful eye on FFXIII and I have to say I am quite confused to say the least.

Here is what I am understand from reading random *insider* info and what not.

FFXIII on PS3 and 360 will have major differences in characters and story but still based in the same world.

Is this true?

And FF:FNC is where I am totally confused. Ive read that it is a spin off of FFXIII, and that it is it's own seperate game nothing alike and everything in between. What is it supposed to be? Is it going to be like FFXII and FFXII:RW? Or similar to the Crystal Chronicles? Or what?

Any help in clearing this up would be awesometastic.
