PSP-Go has a faster processor.

I think everybody is ahead of themselves, the extra 147MHz could be for anything ranging from the bluetooth to the included 16 Gb of flash memory or both. Or the fact that it can multitask (barely) now.

I think the chance of the PSP 4000 being hackable is very low.
As we've seen in the later 2000 production, and the 3000's, Sony is learning to stop CFW with unhackable hardware.
