The "Brain" Of The Revolution

Well not the brain like the ON, but the processor. Read the article here: IBM to Apple: eat these chips.

Toward the end it does confirm that the cell and power PC processors will power the next 3, and there is no way the Revolution will use the cell. So now it's confirmed it will use Power PC, and with the coming of new processors that are designed to have multiple cores and help save power, it only makes sense for Nintendo to use this technology in having a custom built Power PC processor built for them like the Gekko to power the Revolution.
