Sazh's Son and Serah! Sweet!

Excuse the bad attempt at alliteration, and the noticable lack of a link (if one could find one, much appreciated!)

But at Gamescom 2009, 2 new characters were announced.

One is Serah, a silver-haired girl with her hair in a ponytail and Sazh's son, who is currently unnamed. I've heard that they are playable.

Thoughts?

Link to prove this?

GC09: Klee Kuo "Sazh's Son and a New Girl" for FFXIII - Final Fantasy XIII: News, Trailers & Screens ~ Final Fantasy-XIII.net

IGN had an article about it aswell.

I wonder if Serah might be a reference to Princess Sarah from FFI? This is suppose to be a "new beginning for the crystal" and it already seems like the team is referencing some of the earlier games anyway.

Besides, they've reused names before...
