I have to disagree with you on this one.
That may have been true for the previous gen consoles... but the PS3 has what? 1 PPE and 7 SPEs and the 360 has 3 cores with 2 hardware threads each... or instruction pipelines... or whatever they are calling them.
So, if your game code makes use of the PS3's main PPE (it must), and 3 SPE... then you are using what? 100% of the computational potential of the cell? No.
You can measure average CPU usage this way. The max (100%) being all the hardware threads never encountering a WAIT / IDLE / NOP (no operation) instruction.
Does it really mean anything at the end of the day? Probably not, but it IS definately possible that a game is not using 100% of a modern multi-hardware threaded CPU.
