This is pretty big news and could lead to speculation as to which Final Fantasy XIII games are going where.  The obvious rumors are going to be that FFXIII is heading to the Xbox 360 as well as the PlayStation 3.

This quote though could also mean that the series could be heading to the Nintendo DS handheld and or the Nintendo WII as well since Square Enix has been very impressed and pleased with the progression and installed user base of the Wii, with the DS already receiving the Final Fantasy treatment a few times.

Let the rumors begin.  Either way though the fact that Final Fantasy XIII will not be a PS3-exclusive has to make any Sony fan cringe in their gaming chairs.
