Davygee that apples to oranges. System power usage and game completion percentage aren't near the same thing. Square Enix completed the scenario to FFXIII before started coding the game. They know what the total size of FFXIII's world be. They know much text will be containted in the game. They know how many characters the game will feature and how much voice over work those characters will need. In other words, they know how much farther they have to go until they reach 100% complete status.
No one knows the true maximum of the PS3 hardware. The theoritical maxiums listed in the specs are not achievable in actual gameplay situations. The Cell was benchmarked with 8 SPUs, the PS3's Cell only has 6 SPUs available for developers. Thats a one quarter of the potential power of the SPUs gone before the first line of code is programmed.
