Well that chip doesn't even have a usb interface on the pins that are connected to USB D+/D- (but what do I know, I only spent a few hours working on providing diagrams for and big block corrections to 360 JTAG/SPI flasher PIC code.)
Let's see who actually gets it right first. Story developing...
Just because it doesn't use the standard USB port of the pic doesn't mean that's not the chip used. Any 2 pins of a port could be used to "talk" to the ps3 over the USB port. Most likely they have figured out its a PIC18F because of other components like the oscillator and power lines, maybe also other traces left on board for programming or entering the bootloader to program. Once you have identified the programming pins, most PIC programmers will be able to read the chip's ID , easily identifying if its a PIC , Atmal or anything else. Reading back the .hex from the pic might be a little more challenging, as you can protect the code written to them. But that should not be so hard for someone with the right tools.
