If you are a PowerUp rewards member at GameStop and you preorder Final Fintasy XIII-2 from them, you will be receiving an exclusive in-game weapon called the “Genji Bow” for Serah.  The Genji Bow will feature both a sword and bow form, which can be seen below.

It’s a pretty cool little perquisite if you are already a PowerUp member, but definitely not worth signing up just to get this bonus unless you’re that hardcore of an FFF (that’s what I’m calling a Final Fantasy Fan from now on).  Also, the bonus will be retroactive if you already preordered prior to this announcement.
