Sony files for a PS3 change with the FCC, but what?

It seems Sony and the FCC have a little deal going on, as they've
filed for a change regarding the PS3 besides the wireless module.
Sony's letter states that "this is not to cause any modification to the mentioned electric characteristics and RF characteristics". While our mumbo-jumbo isn't fluent, we want to assume Sony is going to create future PS3's with the new 45nm Cell chip inside. That's our two cents, but it's really anyone's guess as this is all just speculation on our part.
