In the latest Dengeki, a new interview with Final Fantasy XIII producer, Kitase, he’s stated that The demo of Final Fantasy XIII will utilize around 50% of PS3‘s capability, whereas the full version will utilize close to 100%”. He related it to how they used the full power of the PSone with Final Fantasy VII and the full power of the PS2 with Final Fantasy X.
He also spoke Blu-ray, “there isn’t really a problem with storage space. However, the PlaySTation 3 also has a hard drive. Depends on which one you are talking about, but there’s still some work to be done on the memory side of things.”
So does this mean it’s using 100% of the Xbox 360‘s power as well?
