Oh Icebeezy, the poor guy on the stage sounds like he's trapped in 2005 during the spec side of things. "The PS3 has a 3.2GHz CPU core but if you have general purpose applications, you cannot really use the vector processor at all because you want to do integer work, want to do branching and so on. This doesn't work on the SPU. So if we compare just the CPU speed the PS3 benchmarks the same as a 1.5GHz G5." It was pretty much a contrived exercise to get the performance difference to be ~2x to the Wii, like he had been establishing for other platforms earlier. I'd dare say he has been taking notes from Deadmeat, which is interesting given the thread you read to find this link...
The actual security part of his speech is interesting though, I'll give you that, but it's nothing we didn't know already sadly.
[edit]Oh right, that would be because it's over 6 months old.
