ARM Trustzone or something. Actually, do they even have it?

That I wonder too. I think hackers are certainly going to try with the PS4 and with the Xbox One, just like they did with the WiiU, for the challenge at least.
I don't expect another XMBC coming out because of them trying, but neither do I expect them just sitting idly by and do nothing.

Now to find that extra ALU 
Cool, confirmation that it's a 20CU part then. We all knew it really but nice to see it confirmed.

Oh PS4 UI is rendered using WebGL https://plus.google.com/+DonOlmstead/posts/Mzy6VEAwHaa
According to that list PS4 has 8.5 GB GDDR5, I have checked the original site, ifixit, and there are only 16, so 8GB.
One thing is unaccounted for though, on the underside of the pcb there's something right at the bottom that looks quite substantial that has not been identified, anyone know what it is?
Is it possible to identify if it's pitcairn, tahiti or Cape Verde from that?

Which one(s) in that list represent the confirmed trueaudio dsp chips?
I think there's a Fujitsu/ARM chip missing (the one near the SATA port).
It might be in the picture above, the southbridge or that other mainboard SCEI chip.
It's none. It's a chip in the same family as Bonaire and Hawaii put part way inbetween both.
If it were released on the PC in it's fully enabled form at a decent clock speed it would be be a straight replacement for the 270/270x. It's a shame we didn't get this instead of the current 270/270x which lacks the slightly more advanced IP as well as TrueAudio.
coldfoot@GAF located the SATA chip:

SATA<->USB bridge.

SATA<->USB bridge.
So is that maybe what ERP hinted at about possibly being HDD speed limited on the PS4, because they have the data drive connected via USB?
This should be pointed out, According to the FCC filing for both the PS4 Dev Kit (https://apps.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout=500&calledFromFrame=N&application_id=435177&fcc_id=AK8DUTD1000) & the retail PS4 (https://apps.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout=500&calledFromFrame=N&application_id=583848&fcc_id=AK8CUH100C1), the PS4 is supposed have Bluetooth 4.0 in addition to Bluetooth 2.1 +EDR. On both of those links, the info is in the last .pdf file called "FCC 15C Report". It should be on page 5.
Now that it's confirmed that the wireless radio in the PS4 is a "Marvell Wireless Avastar 88W8797", we can 100% confirm that the PS4 has Bluetooth 4.0. Here's a link for the .pdf file info on the Marvell Wireless Avastar 88W8797 SoC:

It's USB 3.0 to SATA, the bridge doesn't hit 3GBit in practice, or at least didn't on the benchmarks I've seen.
Interesting that there is no large amount of Flash built in for OS use. Early rumors suggested there would be 16GB on board. Maybe that was back when it was supposed to have 4GB and they thought they'd have to rely heavily on tombstoning to Flash storage for task switching. With the upgrade to 8GB they had the opportunity to reserve more actual memory for multitasking, and the opportunity to partially offset the additional GDDR5's cost.
