Can someone explain to me the room that the test photos are from? Is it sound proof? Why?

Close - radio waves not sound waves.

Turns out that the wavelengths involved are similar, although one form of radiation is acoustic and the other electromagnetic. So those anechoic chambers often work pretty well for both purposes.

Raspberry is the most important project that made my family interested in "computer things" It gathered the whole family together to play old couch-games[0], something that most powerful consoles haven't even been close --specially with the grampas Really exited about what the future will bring us! 0: http://emulationstation.org/

I must be the only one disappointed with old-school games. I was super excited to set up a retropie, after 20 minutes playing the nostalgia wore off quickly. Anyone else find the same?

Also, good on the Pi Foundation for keeping this listing in the open rather than requesting 6 month confidentiality for the pictures/test report (which almost all companies do).

I don't think they did: the confidentiality period is now 45 days only by default, see http://acbcert.com/documents/misc-docs/Memo-Short-Term-Vs-St... Certification took place at Track (now Element UK) on 2015-11-23, given the external picture dates, or 95 days ago, so it looks like it has been extended once.

They didn't request short-term confidentiality for anything: the exhibit summary list at https://apps.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm... has a column for short-term confidential which is all No.

Also, the confidentiality letter would specifically request short-term if they wanted it.

Given Broadcom's connections to the project, it's almost a surprise they didn't have some kind of Broadcom option for WiFi/BT earlier. Must have stung at Broadcom to be powering the most popular hobbyist ARM Linux board, but almost every one using WiFi powered by Realtek,Ralink,etc.

There is an official Raspberry Pi foundation wifi dongle that uses a Broadcom wifi chip with full support in the kernel. For a time it was the only dongle that worked with Windows 10 IoT on the Pi. Can see it here: https://www.adafruit.com/products/2638

All we need is USB 3 and it would be perfect.

I am curious of your application for USB 3? Care to elaborate?

On the Pi 2, the ethernet port was really a USB-to-ethernet port plugged into a hidden USB port. So network speeds were limited to USB 2 speeds. I'm guessing the Pi 3 also works like this, instead of having pure onboard ethernet? But I don't know yet.

I think some of that has to do with the fact that a lot of those older games aren't really as fun as we remembered them to be.

There's some classic gems, to be sure, but they were also all we had.

Earlier quoted context omitted.

Yes, this is the antenna. I cant believe it took them that long, Broadcom is famous for their BT/Wifi chips, buildin wifi was a no brainer, and cost shouldnt be an issue when you have great connections inside the company.

Is a ceramic wifi antenna's range comparable to that of a regular PCB antenna?

Usually slightly better, as it can be a 3D structure.

Comparing the photos to my Pi 2, it doesn't seem very different. There's an extra IC near the microsd card, a connector beneath the HDMI port, and a few other small changes. But nothing that looks like an antenna. Any idea where that might be? Edit: as lovelearning pointed out, there is a small ceramic-looking piece in the upper-left of the top side, near the GPIO pins and LVDS display connector. That might be it.

Look for a cutaway ground plane as a hint to where the antenna may be.
