Ouch -- well that pretty much debunks the ongoing 'Final Fantasy XIII OMGZ Xbox 360' rumors right there. While it seems unlikely that the Xbox 360 will never get another FF game, it appears that for the foreseeable future the PlayStation 3 will be getting all the big name Final Fantasy love. This is fantastic news for Sony and the PlayStation 3, since not only is there a 'slight' dearth of big name third-party exclusives, but also both Final Fantasy VII and Final Fantasy X both helped skyrocket the sales of the PlayStation systems that they were on. And it seems very likely that the same thing will happen with PlayStation 3 sales once FFXIII is released.
Mmm ... the idea that FFXIII is being built exclusively around the PS3 and Blu-ray is pretty exciting. That just makes the wait until next year that much harder though!
